Two pith balls each with mass m are suspended from insulating threads. When the pith balls are given equal positive charge Q, they hang in equilibrium as shown. We now increase the charge on the left pith ball from Q to 2Q while leaving is mass unchanged. Which of the following diagrams best represents the new equilibrium configuration:- Do we consider them as point charges and use Coulombs law? Since the mass is unchanged and The Fe = Kq1q2/r^2 on both the charges. then why isnt both the angles same? My basics are weak and so I need to strengthen it
