Question

Two charges each of one coulomb are placed at a distance of 0.3m apart in air. Calculate the force between them


​

Answer 1

Explanation:

Distance between the spheres, A and B, r = 0.5 m

Initially, the charge on each sphere, q = 6.5 × 10−7 C

When sphere A is touched with an uncharged sphere C, (q/2) amount of charge from A will transfer to sphere C. Hence, charge on each of the spheres, A and C, is (q/2).
