1. The volume charge density of a solid sphere of radius
R
varies as
ρ = ρ
0
(
r
R
)
, where
ρ
0
is a constant (of appropriate unit) and
r
is the radial distance measured from the
center of the sphere. Find out the electric field at a distance
s
from the center of the sphere
by calculating the contribution due to an infinitesimal volume and then integrating over the
volume of the sphere.
