1. The problem statement, all variables and given/known data I am given V(x,y,z) = 3x^2 + 2y + 5 and I am given s = (5,3,1), so what is the electric field? 2. Relevant equations V= Es 3. The attempt at a solution I really have no idea. What I tried: Derivative of V(x,y,z) = 6x+2 so E = 32 N/C? Really I just don't understand the math necessary. How is it done?
