A) 5J
B) 10J
C) 20J
D) 2.5J
Correct Answer: B
Solution :
(b) 10J Here, \[V=200\text{ }V,q=0.1\text{ }C\] Energy stored, \[U=\frac{1}{2}qV\] \[=\frac{1}{2}\times 0.1\times 200=10\,\,J\] When the capacitor is discharged, it releases the same amount of energy i.e., 10 J.You need to login to perform this action.
