1. The problem statement, all variables and given/known data Find the electric field of a sphere of radius R and charge Q outside sphere. Use only a Coulomb integral to do this. 2. Relevant equations I know that I have to use a triple integral to find the E-field. I am just unsure of my whole setup really. 3. The attempt at a solution I tried setting up a triple integral of (0-2pi),(0,R) and then I dont know what to put for the the bounds of the third.
