posted by Anonymous on .
Two pith balls equally charged and each with a mass of 1.5. White one ball is suspended by a thread, the other is brought close to it and a state of equilibrium is reached. In that situation, the two balls are separated by 2.6cm and the thread attached to the suspended ball makes an angle of 20deg with the vertical. Calculate the charge on each of the pith balls
