What happens when a positively charged rod touches an electroscope?
If you bring a positive object near the electroscope, it will attract the electrons toward the terminal. The leaves will move away from each other. You can also use this process with a positive object to charge the electroscope.
What happens to a positively charged electroscope?
When a positively charged electroscope is touched, electrons enter the electroscope from the ground. Being positively charged, the electroscope attracts some electrons from the conducting material (in this case, a person). The negatively charged electrons enter the electroscope and neutralize the positive charge.
What happens to the electroscope and to the charges if a positively charged object comes in contact with the electroscope?
If a charged object is brought near the top of the electroscope, the leaves at the bottom spread apart. The greater the charge, the farther apart they move. When a positively charged object is brought near the knob, the electrons in the leaves move towards the other end being attracted by the rod.
What happens to the positively charged glass rod and to the electroscope when the rod came in contact with the ball of electroscope?
(b) When the rod is touched against the ball, electrons are attracted and transferred, reducing the net charge on the glass rod but leaving the electroscope positively charged.
What happens to the electrical charges when a charged metal rod is placed near the electroscope?
When the negatively-charged rod is brought close to the electroscope, positive charges are attracted to it and negative charges are repelled away from it.
Where would the electrons in this electroscope go if a positive Rod came near?
Similar to the results of a negatively charged rod, if a positively charged rod is brought near the knob of a neutral electroscope, it will attract some electrons up from the leaves onto the knob. That process causes both of the leaves to be positively charged (excess protons), and the leaves will diverge.
What happens when a positively charged rod is brought near a negatively charged electroscope?
When a positively charged rod is brought near the cap of a positively charged electroscope?
When a positively charged rod is brought near the positively charged cap then, the positive charge on the cap will spread over because of repulsion and some of them will reach the leaves. Now, the leaves will have the same positive charge, they will repel each other and hence, leaves will diverge.
What is the charge on the body if the leaves of positively charged gold leaf electroscope diverge when a body is brought near it?
Hence, the charge on the body is negative.
What happened to the electrical charge when a charged metal rod is placed near the electroscope?
When a negatively charged object is brought close to a positively charged electroscope does the divergence of its leaves decrease or increase?
Therefore, when a negatively charged object brought close to positively charged electroscope the divergence of its leaves decreases as unlike charges attract each other.
When a positively charged rod is brought near the cap of a positively charged electroscope the leaves divergent will?
Since the charged rod is not in contact with the electroscope, the leaves divergence will diverge.
What will happen to the leaves of an electroscope if a positively charged body is brought near a an uncharged electroscope and B positively charged electroscope 1 point?
Solution : (a) Diverge (b) Will diverge further ( c ) First converge and then again may diverge.
What happens to the leaf of a gold leaf electroscope when the same charge is put on it?
Both the gold leaves will have same charge and hence as a result they will repel and diverge. The degree of divergence is an indicator of the amount of charge i.e., more the charge, more will be the divergence.
What happens when a positively charged object is brought near a negatively charged object?
That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart. Similarly, a negatively charged object will exert a repulsive force upon a second negatively charged object. Objects with like charge repel each other.
What will happen to the leaves of an positively charged electroscope if a positively charged body is brought near?
A charged body is brought near a positively charged gold leaf electroscope. The divergence of its leaves increases.
When a positively charged rod is brought near a negatively charged electroscope then leaves will?
These electrons go to the gold leaves, and due to increased repulsion due to increased number of electrons, the leaves will be diverged. If it is brought near a positively charged electroscope the leaves will fall closer together.
What happens when you bring a positively charged rod to electroscope?
When you are bringing the positively charged rod near the electroscope, we express that electrons will gather near the charged rod leaving a net positive charge on the electroscope leaves, as you have shown in the diagram.
How is an electroscope charged?
This figure shows an electroscope being charged by touching it with a positively charged glass rod. Because the glass rod is an insulator, it must actually touch the electroscope to transfer charge to or from it.
How much polarization of charge will happen on an electroscope?
The amount of polarization of charge that will happen on the electroscope will depend on how much net positive charge does the rod contain. A rod with charge q 1 will cause more electrons to get accumulated on the ball as oppose to q 2 charge, where q 1 > q 2.
What is the electric potential of the knob of the electroscope?
The rod and the knob of the electroscope, separated by a variable gap, are modeled as a variable capacitor, C var. The electroscope is represented by a fixed capacitor, C e. Initially the gap is large and C var =0. In situation 1 and 2, the gap is minimal and C var =C var,max. The electric potential of the knob, V’, is variable.
