An uncharged electroscope can tell the nature of charge on a charged body .

An uncharged electroscope can be charged by holding a charged body near its cap. ____________

A charged body is held near the disc of positively charged GLE. It is found that leaves of GLE diverge more. The nature of charge on the charged body is :

In case of electronic current the charge flows from negatively charged body to the Positively charged body. The body which is at higher potential is :

When charge is given to a body

What will happen to the leaves of an electroscope if a positively charged body is brought near (a) An uncharged electroscope ? (b) A positively charged electroscope ? ( c ) A negatively charged electroscope ?

Prove that, if an insulated, uncharged conductor is placed near a charged conductor and no other conductors are present, the uncharged body must be intermediate in potential between that of the charged body and that of infinity.

When a negatively charged ebonite rod is brought close to an uncharged electroscope, the leaves of the electroscope develop positive charge and diverge.

A glass rod rubbed with silk is used to charge a gold leaf electroscope and the leaves are observed to diverge. The electroscope thus charged is exposed to X -rays for a short period. Then

When a negative charged rod is brought near, but does not touch, the initially unchanged electroscope shown below, the leaves spring apart (I) . When the electroscope is then touched with a finger, the leaves collapse (II) . When next the finger and finally the rod are removed, the leaves spring apart a second time (III) . The charge on the leaves is

A charge Q is placed at the centre of an uncharged, hollow metallic sphere of radius alpha. (a) Find the surface charge density on the inner surface and on the outer surface. (b) If a charge q is put on the sphere, what would be the surface charge densities on the inner and the outer surface?
