24. Electric Force & Field; Gauss' Law
Electric Fields in Capacitors
An electric dipole consists of point charges +q and -q. At a point on its axis, 2.3 cm from the center, the electric field strength is 7.3 × 10⁷ N/C. Calculate the charge Q (in μC) needed for a single charge to produce the same field strength at a distance of 2.3 cm.
