The electric potential field Vat a point, due to two charged particles, is given by V=- 92 4 where q, and 42 are the charges of the particles in coulombs (C), r, and ry are the distances of the charges from the point (in meters), and so is the permittivity of free space, whose value is Ep = 8.854 x 10-12 c2 AN m2) Suppose the charges are 91 = 2 x 10-10 C and 92 = 4 x 10-10 C. Their respective locations in the xy plane are (0.3, 0) and (-0.3, 0) m. Plot the electric potential field on a three-dimensional surface plot with Vplotted on the z axis over the ranges -0.25 s x 5 0.25 and -0.25 s y s 0.25. Create the plot in two ways: (a) by using the surf function and (b) by using the meshc function
