1. What must the charge (sign and magnitude) of a 1.45 g particle be for it to remain stationary when placed in a downward directed electric frield of magnitude 650N/C? also What is the magnitude of an electric field in which the electric force on a proton is equal in magnitude to its weight.

What do I do?

Compute the gravitational force and the electric force and set them equal and opposite, right? What else would you do?
