A proton is accelerated through `50,000 V`. Its energy will increase by

A

`5000 eV`

B

`8 xx 10^(-15)J`

C

`5000 J`

D

`50,000 J`

Text Solution

Verified by Experts

The correct Answer is:
B
kinetic energy `K = Q.V rArr K = (+e) (50000V)`
`= 50000eV = 50000 xx 1.6 xx 10^(-19) J = 8 xx 10^(-15) J`
