Obtain the magnitude of the electric field in the room

Reference no: EM13525902

A small 12.3g plastic ball is tied to a very light 26.6cm 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 -1.10mc , 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?
