Is there any conductor which can be given unlimited charge?

Can there be potential difference between two adjacent conductors which carry the same positive charge?

The dielectric constant of a conductor can be taken to be infinitely large, infinitely small or optimum. Which of the three alternatives is correct?

A and B are two negatively charged and insulated conductors. State, with reason, which conductor will tend to lose charge?

Describe with the help of a diagram an instrument which can be used to detect a charged body.

A conductor A with a cavity as shown in Fig. is given a charge Q.. Another conductor B with charge q is inserted into the cavity keeping B insulated from A. Show that the total charge on the outside surface of A is Q + q .

How many electrons must be removed from a conductor so that it acquires a charge of 3.5 nC ?
