= Find the electric field (magnitude and direction) at a point P = (0,0,z), a distance z above the midpoint between two opposite charges of magnitude q, a distance d apart (see figure below). Check that your result is consistent with what you'd expect when z » d (Hint: find in Griffiths the expression for the far-away electric field of a dipole). Then enter the numerical value for the magnitude of the electric field for the case (all quantities in SI units) z = 13.11, q = 9.71 x 10-7, d = 1.42. P 2 T d/2 d/2 9 -9 Find the electrostatic potential V at any point (x,y,z) in space for the two charges illustrated in the figure below. Check your answer by computing E= -VV at a distance z above the midpoint between the two charges, and comparing your answer to that obtained in Question 1. Then, given that q = 8.8 x 10-7 and d = 8.1, enter the numerical value of V at the point (x, y, z) = (2.8, 7.1, 1.3). where all quantities are specified in SI units. P d/2 d/2 9
