Problem 22.12: Charge on a tabletop
Please wait for the animation to completely load.
A charged ball of mass 100 grams is placed on a frictionless tabletop with a second charge fixed underneath. Play the animation and observe the motion. You may drag the charged ball to any position before beginning the animation. Restart.
If the charge of the fixed charge (beneath the table) is negative 2 μC, determine the value of the charge on the ball. (Show hint.)
