Textbook Question
Chapter 17, Problem 69GP
A small 12.3 g plastic ball is tied to a very light 28.6 cm string that is attached to the vertical wall of a room. (See Figure 17.61.) A uniform horizontal electric field exists in this room. When the ball has been given an excess charge of −1.11 µC, you observe that it remains suspended, with the string making an angle of 17.4° with the wall. Find the magnitude and direction of the electric field in the room.
