Problem 1 (40 pts) If there is a line L (y = 1, z = 1) carries charge with density = 20 nC/m; there is a plane at x = 4 carrying 10 nC/m2 and there is a point charge of 5 nC located at (-3, 4, 0). Please (i) calculate E at (2, 2, -2); (ii) if V=0 at O(0, 0, 0), find V at P(1, 0, 2)

would you solve it in clear and concise way and if u can copyable too. please note there is many answers online but can not read or figure it out.

thanks
