Surface Volume and Line charge densities, how to solve problems?

$
0
0
This question is a perfect example:

A solid sphere 25cm in radius carries 14microC, distributed uniformly throughout it's volume. Find the electric field strength a) 15cm b)25cm and c)50 cm from center.

I know that I need my gaussian surface and I also need
p=q/v where p is the (Qenclosed) in the equation: Qenclosed/epsilon=EA

Could someone help me understand what the charge densities are for. Do I have to subsitute Qenclosed for p or do I just use it as a clue that I need the volume?

Thank you for your time!!

Warmest regards,
