1. The problem statement, all variables and given/known data The electric potential in a certain region is V = 10x^2 -12x + 63 Determine the electric field at x = 3m. Answer in units of V/m. Determine the position where the electric field is zero. Answer in units of m. 2. Relevant equations E = -(partial derivative V / partial derivative X) 3. The attempt at a solution I took the derivative of V : V' = 20x -12 E = -20x + 12 I plugged in 3 for x and found that the electric field is -48 V/m. To find the second part of this problem, I used the same equation and set E = 0. I found x to be 0.6 m. Is this the right way to work this problem? Thanks.
