Question
A point charge Q of mass 8.50 g hangs from the horizontal ceiling by a light 25.0-cm thread. When a horizontal electric field of magnitude 1750 N/C is turned on, the charge hangs away from the vertical as shown in Fig. 21.6. If the charge is 12.5-cm from the vertical, the magnitude of Q is closest to:
