Question

A parallel plate air condenser is connected with a battery. Its charge, potential difference, electric field and energy are Q 0, V 0, E 0, and U 0, respectively. In order to fill the complete space between the plates a dielectric slab is inserted, the battery is still connected. Now the corresponding values Q, V, E and U are in relation with the initially stated as

(1) V > V 0

(2) Q > Q 0

(3) E > E 0

(4) U > U 0

Question

Assertion (Ꭺ)

No work is done in taking a small positive charge from one point to other inside a positively charged metallic sphere while outside the sphere work is done in taking the charge towards the sphere. Neglect induction due to small charge.

Reason (Ꭱ)

Inside the sphere electric potential is same at each point, but outside it is different for different points.
