What is the charge on the ball bearing

Reference no: EM13712509

Problem: A small glass bead has been charged to + 20.0nC. A metal ball bearing 2.80cm above the bead feels a 1.20 × 102 N downward electric force.

Part A: What is the charge on the ball bearing?

Any help I can get on this problem is really appreciated! I'm not too familiar with this problem.
