(chatquestion)...A charge Q is distributed over three concentric spherical shells of radii a, b, c (a <b< c) such that their surface charge densities are equal to one another. The total potential ot a point at distance r from their common centre, where r < a, would be Q ab+bc+ca (a) 4tE,(a+b+c) (b) 12TEO abc Q(a² +b² +c) Qla +b+c) (c) 4TE (a²+b²+c²) (January 2019)
