1.) A 5.99?C and a -2.04?C charge are placed 16.2cm apart.
Where can a third charge be placed so that it experiences no net force? [Hint: Assume that the negative charge is 16.2cm to the right of the positive charge.
2.) A downward force of 3.0 N is exerted on a -8.4?
a.) What is the magnitude of the electric field at this point?
b.) What is the direction of the electric field at this point?
