Q. 7 In the circuit shown in the figure, initially uncharged metal balls with radii a, b & a are connected with points 1, 2 & 3 respectively with long thin conductors. Consider the distance between the balls to be much larger than their size, the charge on the electrical circuit itself and on the connecting conductors is negligible and the internal resistance of battery is zero. Choose the CORRECT statement(s). E is emf of the battery. E R R 1 ww 2 ww 3 a a b
