A foam ball of a mass of 0.150 g carries a charge of -2.00 nC. The ball is in a uniform electric field, and is suspended against the force of gravity. What are the magnitude and direction of the electric field?

M g = E Q

Solve for the field magnitude E. You will need the value of g, which I am sure you already know.

The direction of the E-field is down, so that an upward force is applied to a negative charge.
