Solve the all parts of following question:
Question: The electric potential in a region of space is V(x, y, z) = (x+y-3y2)V, where x, y and z are in meters.
Part A: What is the electric field vector, as a function of the three Cartesian coordinates x, y, z?
Part B: What acceleration would this field exert on a proton located at the origin?
I need the right answer and steps of solving these questions. Thanks!
