An electric field in a region of space is parallel to the x axis. The electric potential varies with position as shown in Figure P25.36. Graph the x component of the electric field versus position in this region of space.
The Attempt at a Solution
The green is the -grad V or just -dV/dx, at x = 2 to 3, I am just wondering, that is 0, but should I put a dot on the origin?
