A body of capacity 
is charged to 
and another body of capacity 
is charged to 30V. When they are connected the energy lost by 
capacitor is
Text Solution
Verified by ExpertsThe correct answer is:
A
Initial energy of body of capacitance 4 μ μ F is 
Final potential on this body after connection is 
So final energy on it
Energy lost by this body = U i – U f = 7.8 mJ
