A Point Charge Q of Mass 8

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 the figure. The magnitude of Q is closest to

A) 27.5 µC.
B) 47.6 µC.
C) 55.0 µC.
D) 3.0 µC.
E) 3.5 µC.
