The figure shows a conducting sphere 'A' of radius 'a' which is surrounded by a neutral conducting spherical shell B of radius 'b' `( gt a)` Initially switches `S_(1),S_(2)` and `S_(3)` are open and sphere 'A' carries a charge Q.

First the switch `'S_(1)'` is closed to connect the shell B with the ground and then opened Now the switch `'S_(2)'` is closed so that the sphere 'A' is grounded and then `S_(2)` is opened Finally, the switch `'S_(3)'` is closed to connect the spheres together. Find the heat(in Joule) which is produced after closing the switch `S_(3)` [Consider `b=4 cm a=2 cm and Q=8muc]`
