. A solid metal cube has 10 nC of charge placed on it.

a) Much charge is at the center of the cube?

b) What is the electric field at the center?

The earth has an electric field of approximately 150 N/C directed downward. If a dust particle with as mass of 10 µg has -10 nC of charge, what is the net force on the particle?
