A wall has a negative charge distribution producing a uniform horizontal electric field. a small plastic ball of mass 0.0242 kg, carrying charge of −103 µc, is suspended by an uncharged, nonconducting thread 0.274 m long. the thread is attached to the wall and the ball hangs in equilibrium in the electric and gravitational fields, as shown. 0 − .274 m − − − − − − − x y z (out) 0.0242 kg −103 µc find the magnitude of the electric field at the ball’s location due to the charged wall. assume the electric force on the ball has a magnitude of 0.0347 n. the acceleration due to gravity is 9.8 m/s 2 . answer in units of n/c
