# Calculate the electric field everywhere.

Not what you're looking for?

A spherically symmetric charge density occupies the region r<a. The charge density increases with radius as rho(r)=(rho,o)r^2 where rho,o is a constant. Calculate the electric field everywhere.

##### Solution Summary

Solution uses Gauss Law to solve for the electric field when r>a, r = a, and r<a.

##### Solution Preview

For r<a
By Gauss Law,
flux*eps = total charge
=>E*4pi*eps*r^2 = integration(0 to r) [rho_o*r^2*4pi*r^2*dr]
=> ...
