Homework Help: Physics-Charges

Posted by Joila on Wednesday, March 7, 2012 at 6:32pm.

A wall has a negative charge distribution producing a uniform horizontal electric field.
A small plastic ball of mass 0.0261 kg, carrying charge of −102 μC, is suspended by an uncharged, nonconducting thread 0.369 m
long. The thread is attached to the wall and the ball hangs in equilibrium in the electric and gravitational fields.

Find the magnitude of the electric field at the balls location due to the charged wall. Assume the electric force on the ball has a magnitude of 0.0363 N. The acceleration due
to gravity is 9.8 m/s2 .
Answer in units of N/C
