Consider a long uniformly charged, cylindrical insulator of radius R with charge density 1.1 micro-coulombs/m^3. (The volume of a cylinder with radius r and length l is V = pi*r^2*l)(adsbygoogle = window.adsbygoogle || []).push({});

What is the magnitude of the electric field inside the insulator at a distance 2.7 cm from the axis (2.7 cm < R)? Answer in units of N/C.

------------------------------------

The axis they are referring to in the problem runs through the cylinder from top to bottom...

i dont really know where to go with this problem. any pointers/tips/starting points would be great.
