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.

Question

Two identical thin rings each of radius R meters are coaxially placed at a distance R meters apart. If Q 1 coulomb and Q 2 coulomb are respectively the charges uniformly spread on the two rings, the work done by external agent in moving a charge q slowly from the center of ring with charge Q1 to that of other is,
