How To Find Potential ?? 1. The problem statement, all variables and given/known data Consider the uniformly charged sphere with radius R = 4.65461 m, Q = 6.66731 μC is the total charge inside the sphere. a) Find the total flux passing through the Gaussian surface (a spherical shell) with ra- dius 2.08762 m. b) Find the electric field at radius r = 2.08762 m. c) Find the value of the electrostatic potential at the same radius r = 2.08762 m. 2. Relevant equations E=kq/r^2 v=kq/r 3. The attempt at a solution I have answered Parts A & B , I got for part A : Total Flux = (Q/Epsilon)*(r/R)^3 & for part B : E = kQr/R^3 , But part C have stopped me so any hint or clue will be gratefull and thx in advance.
