A parallel plate capacitor is charged to a potential difference of 50V. It is discharged through a resistance. After 1 second, the potential difference between plates becomes 40V. Then

fraction of stored energy after 1 second is 16/25.

potential difference between the plates after 2 seconds will be 32 V.

potential difference between the plates after 2 seconds will be 20V.

fraction of stored energy after 1 second is 4/5.
