A charged particle (charge `q`) is moving in a circle of radius `R` with unifrom speed `v`. The associated magnetic moment `mu` is given by

A

`qvR^(2)`

B

`qvR^(2)//2`

C

`qvR`

D

`qvR//2`

Text Solution

Verified by Experts

The correct Answer is:
D
Magnetic moment `M=IA`
But `I=(dq)/(dt)` or `q/T=(qv)/(2pi R)" "[ :. T=(2pi R)/v]`
`:. M=IA=(qv)/(2pi R)xxpi R^(2)`
`M=(q vR)/2`
