A solid conducting sphere of radius 10 cm is enclosed inside a thin, metallic shell of radius 20 cm. A charge of 1 μC is given to inner sphere. How much heat is generated in process when inner sphere is connected to shell by a conducting wire
22.5 mJ

2.25 J

9.0 mJ

6.2 mJ

Answer 1

Answer:

9.0J

Explanation:

A solid conducting sphere of radius 10 cm is enclosed by a thin metallic shell of radius 20 cm.

A charge q = 20 mu C is given to the inner sphere is connected to the shell by a conducting wire

=(20×10-6)×9×1092[10.01-10.20]

=9.0J.
