A charged particle revolves in circular ...

A charged particle revolves in circular path in uniform magnetic field after accelerating by a potential difference of V volts. Choose the correct options if `V` is doubled.

A

kinetic energy of particle will become two times

B

radius in circular path will become two times

C

radius in circular path wil become `sqrt2` times

D

angular velocity will remain unchanged

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
`KE=qV` or `KEpropV`
`r=sqrt((2qVm))/(Bq)` or `rpropsqrtV`
`T=(2pim)/(Bq)` or `T` independent of `V`.
