A region in space has an Electric field given by E = x(x^) - y(y^) + xy(z^) where (x^), (y^), (z^) indicate corresponding letter with caret on top of it.
A charge of 1 uC moves along a straight line with constant velocity from (0,0,0) to (1m,1m,1m). What is the gain in energy for the charge?
Please provide a step by step solution.
