Find the magnitude of the electric field in the room

Reference no: EM13486641

A small 12.5g plastic ball is tied to a very light 27.8cm string that is attached to the vertical wall of a room. A uniform horizontal electric field exists in this room. When the ball has been given an excess charge of -1.10?C , you observe that it remains suspended, with the string making an angle of 17.4? with the wall.

Find the magnitude of the electric field in the room.
