Two styrofoam balls with the same mass m = 9.00 × 10−8 kg and the same positive charge q are suspended from the same point by insulating threads of length l = 0.705 m. the separation of the balls is d = 0.0221 m. what is the charge q?

Explanation:

As we know that the two styrofoam balls are suspended in equilibrium

so we will have

also we know that

so we will have

now from above two equations we have

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
