A glass rod rubbed with silk is brought close to two uncharged spheres in contact with each other, inducing charges on them . Describe what happen when:- The spheres are separated far apart.

A glass rod rubbed with silk is brought close to two uncharged spheres in contact with each other, inducing charges on them as shown in figure. Describe what happen when:- The glass rod Is subsequently removed.

A glass rod, when rubbed with silk cloth, acquires a charge 1.6 x 10^(-13) Coulomb. What is the charge on the silk cloth.

What will happen to two soap bubbles of different radii, which are in contact with each other? Why?

What is the force of repulsion if each sphere charged double the above the amount and the distance between them is halved ?

When a glass rod is rubbed with a silk cloth, charges appear on both. A similar phenemenon is observed with many other pairs of bodies. Explain how this observation is consistent with the law of conservation of charge.
