(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A long cylindrical insulator has a uniformcharge density of 1.46uC/m3 and a radius of 6cm.

a-What is the electric field inside the insulator at a distance of 2cm and 12cm? Answer should be in N/C.

b-How much work must you do to bring a q=0.086uC test charge from 12cm to 2cm? Answer in J.

2. Relevant equations

I have started with p=Q/V. With V= [tex]\pi[/tex]r^{2}h

3. The attempt at a solution...yet there is no h??

I know for r>R and r<R there are differences. I am lost. Please someone point me in the correct direction.
