a) For the arrangement of charges in the figure, calculate the
electric potential (in V) at point P. Use q = 3.0 nC and d = 2.7 m,
and assume that V = 0 V at infinite distance.

In this exercise you will figure out the equipotential point/points(s)/line/surface in the xy plane where V = 0 for two point charges of charge q and -2q found respectively at (x,y,z) = (-1,0,0) and (x,y,z) = (1,0,0), and draw the result on Fig. ??. (a) Given that V is a scalar, equipotentials generally form surfaces in three di- mensions. This contrasts with the electric field, where we found only one position where it was zero for a pair of point...
