Two point charges are on the x-axis. Charge 1 is +1 nC and is located at x = -1.0 m; charge 2 is -2 nC and is located at x = 1.0 m. a) Draw the charges and sketch out the electric field lines in the area around the charges (show at least 8 electric field lines). b) Indicate which regions the magnitude of the electric field is large, small, or zero. c) Calculate the direction and magnitude of the electric field at the point (x = 0.25 m, y = 0.5 m). d) Draw two distinct equipotential surfaces and calculate the potential on each one
