Ans: Q1=(10/19)3Q
Q2=Q3= - Q1/5
Now solve and check your ans.
Three balls of radii 'R' are placed at the corners of an equilateral triangle of side 4R. Ball 1 is given charge +Q and balls two and three are earthed. A fourth identical ball placed very far from this system is connected to ball 1 by a thin conducting wire and disconnected. Now fourth ball is connected to ball 2 and then disconnected from it. Again connected to ball 1 and disconnected. Now it is connected to ball 3 and disconnected and finally connected to ball 1 and disconnected. Find the final charge of all the balls.
