A small plasticl ball is tied to a very light 26.0 cm string that is attached to the vertical wall of a room. A uniform horizontal electric field of magnitude 36,000 N/C exists in this room. When the ball has been given an excess charge Q = -1.10 uC, you observe that the ball remains suspended, with the string making an angle of 17.4 degrees with the wall.
A) What is the direction the electic field E in the room?
B) what is the magnitude of the electric force exerted by the field on the ball?
C) What is the mass of the ball?
