Two identical charged particles enter a ...

Two identical charged particles enter a uniform magnetic field with same speed but at angles `30^(@)` and `60^(@)` with field Let a,b and c be the ratio of their time periods, radii and pitches of the helical paths than .

A

`abc =1`

B

`abcgt1`

C

`abc lt 1`

D

`a =bc`

Text Solution

Verified by Experts

The correct Answer is:
A,D
`r =T = (2 pim)/(qB) a =1`
`r =(mV_(1))/(qB), b = (sin 30^(@))/(sin 60^(@)) = (1)/(sqrt3)`
Pitch a `v cos0 c = (cos 30^(@))/(cos 60^(@)`
`So abc =1` .
