Text Solution
Verified by ExpertsD
The electric field intensity at a point lying outside the sphere (non-conduction) is
where, 
is the distance of that point from center of sphere.
… (i)
The electric field intensity at surface of sphere,
… (ii)
where R, radius of sphere.
The electric field intensity at a point lying inside the sphere is
or 
… (iii)
Also, at the center of sphere 
. Hence, 
. The graphical distribution is shown below.
