A particle has a mass `400` times than that of the elctron and charge is double than that of aelectron. It is accelerated by `5 V` of potential difference. Initially the particle was at rest, then its final kinetic energy will be

A

`5eV`

B

`10 eV`

C

`100eV`

D

`2000 eV`

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaE = 2e xx 5V = 10eV rArr` Final kinetic energy `= 10eV`
