# #2015_27 How well you know about electric field?

A non-conducting solid sphere has volume charge density that varies as $$\rho ={ \rho }_{ 0 }r$$ where $${ \rho }_{ 0 }$$ is a constant and $$r$$ is distance from center. Find out electric field intensities at $$r<R$$, where $$R$$ is the radius of sphere.

Given,

$$R$$= 4 meter

$$r$$= 2 meter

$${ \rho }_{ 0 }$$= $$8.854\times { 10 }^{ -11 }$$
