## Homework Statement

Two tiny conducting spheres with a mass of 14 gm each are hanging from non-conducting threads of length 60 cm such that they are 6 cm apart. What is the electrical force between the spheres?

## Homework Equations

f = m*g*tan(theta)

## The Attempt at a Solution

0.6^2 - 0.03^2 = length y = 0.599249531

theta = tan^-1(0.03/0.599249531) = 2.865983 degrees

F = 14*9.81*2.865983 = 393.6142N

Which does not seem right to me. I think I messed up the angles but no entirely sure.
