## Enginering Electromagnetics help

1. The problem statement, all variables and given/known data
The charge density throughout a region is give by pv=10e^-3r{uC/m^3}, where r is measeure in meters. Find the total charge Q contained in a sphere center about the origin that has a radius of meters.

Where e = -1.60210X10^-19

2. Relevant equations
e = -1.60210X10^-19
volume of a sphere = 4/3śr^3

3. The attempt at a solution

didnt know where to start

 The following should help. Regards, Nacer.
 Yeah, I figured out that part i just have trouble integrating the problem. I get some huge number when I do that. But I do appreciate you showing me that but, if you could can you show me how its worked out. The answer is 8.73microCoulombs. Thanks again
