A pith ball of mass 0.05 gm carries a charge 100 e.s.u. A metallic charged ball wh is 10 cm directly above the pith ball can hold the pith ball in equilibrium. The cha on the metrallic ball is : (а) — 49 е.s.u (b) - 10 е.s.и (с) + 15 e.s.u (d) - 30 e.s.u - | A drop of mercury is raised to a potential of 90 volts. This is broken into 27 ident Irops. The potential of each droplet is : (a) 2 volts (b) 5 volts (c) 10 volts (d) 15 volts. pith ball carrving
