Problem 22.11

Please wait for the animation to completely load.

A 20-gram charged ball is connected to a spring and placed on a frictionless tabletop as shown (position is given in meters and time is given in seconds).  Restart.

1. Find the equilibrium position.
2. Find the spring constant.

Add a 2-μC charge on the right-hand side of the table.

3. Has the spring constant changed?  Explain.
4. Find the new equilibrium position.
5. What is the charge on the ball?
