# Physics problem

This is an interesting problem I found.
It's a beginner physics problem….

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?
