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?
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.
