Two charged spherical conductors, each of radius R, are distant d (d lt 2R) . They carry charges +qand -q will the force of attraction between them be exactly(q^(2))/(4pi in _0d^(2))? Give reasons of your answer.

Answer»

Solution :No , the force of attraction between charged spherical conductors will be more than `(q^(2))/(4PI in _0d^(2)) ` . On account of MUTUAL attractive force there will be a REDISTRIBUTION of charges on the spheres as shown in As a result, EFFECTIVE distance between them is reduced and the force increases.
