A wall has a negative charge distribution producing a uniform horizontal electric field. A small plastic ball of mass 0.01 kg, carrying a charge of -80.0 μC, is suspended by an uncharged, nonconducting thread 0.30 m long. The thread is attached to the wall and the ball is suspended in equilibrium in the electric and gravitational fields. The electric force on the ball has a magnitude of 0.032 N.
(a) Calculate the magnitude of the electric field due to the negatively charged wall at the ball's location.
(b) Calculate the horizontal distance between the wall and the ball.
