Two small spheres hang in equilibrium at the bottom ends of threads, 40.0 cm long, that have their top ends tied to the same fixed point. One sphere has mass 2.40 g and charge +300 nC. The other sphere has the same mass and charge +200 nC. Find the distance between the centers of the spheres.

As seen from the figure, the balanced forces on a charged sphere are:
 
 
Now, we assume that h ? 40 cm as the angle is very small.
 
Thus, we get
 
Now, the electrostatic force between the two charged spheres is
 
 
Thus, we have
 
Thus, we have
