This is an interesting problem I found.

It's a beginner physics problem….

(sorry for bad formatting)

A small insulating ball of mass \( m=1.0 mg\) and charge \( q = 2.0\cdot 10^{-8}C \) distributed uniformly throughout its volume, hangs from an insulating thread that makes a \( 30^{\circ}\) angle with a vertical, uniformly charged nonconducting sheet. If the ball is in equilibrium, what is the charge density on the vertical sheet?
