Please solve this physics question​

Answer 1

Answer:

C)44%

Explanation:

Energy stored in a capacitor with potential difference

V applied across it is 1/2 CV 2 =E0.

when potential difference increases by 20%,

V'=1.3V

=E' =1/2CV'2 =1/2C(1.2^2V2)

=E'=1.2^2E0=1.44E0

Thus the energy stored increases by 44%.

Answer 2

Explanation:

44 %
