A positively charged particle Q_1 = 45 nC is held at fixed position. A second charge Q_2 of mass m=7.5 ug is located a distance d=25cm directly above charge Q_1. The net force on charge Q_2 is equal to zero. Calculate the magnitude of Q_2 in units of nanocoulombs
Added by Derek B.
Step 1
Since Q_1 is positively charged, it will exert an electrostatic force on Q_2. For the net force on Q_2 to be zero, there must be another force acting on it that balances the electrostatic force. This could be the gravitational force acting downward. Show more…
