qis placed in a spherical cavity made in a positively charged sphere with uniform volume charge density The centres of sphere and cavity are displaced by a small distance 7 Force on charge qis A B C D do midt in the direction parallel to vector 7 in radial direction with respect to centre of cavity in a direction which depends on the magnitude of charge density in sphere direction cannot be determined
