Homework Statement
A ball is at a known height on a certain ramp with an unknown angle theta. The ball has a known charge and a known mass. There is also a known charge at the bottom of the ramp. I am supposed to find the angle theta.
Homework Equations
F=(8.988x10^9)q1q2/d^2 F=mgsin(theta)
The Attempt at a Solution
How do I incorporate theta into the electric force equation? Do I just multiply d^2 by theta? Then I would set the two equations equal and solve for theta: Is that correct? It does not seem to be working for me. Thanks/
