a
Electrical field intensity due to a non-conducting charged solid sphere at a point outside the sphere is R3ρ3∈0r2
b
Electrical field intensity at a point on the surface of a insulating charged solid sphere will be Rρ3∈0
c
Electric field intensity due to an insulating charged solid sphere at a point located inside the surface at a distance ‘r’ from the centre of the sphere will be ρr3∈0
d
Electric field intensity due to a solid insulating charged sphere, at a point inside the sphere will be zero
answer is D.
