The magnetic force on a point moving ch...

The magnetic force on a point moving charge is `F=q(vxxB)`.
Here `q=` electric charge
`v=` velocity of the point charge
`B=` magnetic field
The dimensions of `B` is

A

`["MLT"^(-1)"A"]`

B

`["M"^(2)"LT"^(-2)"A"^(-1)]`

C

`["MT"^(-2)"A"^(-1)]`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Magnetic force, F=`q`(v`xx`B)
or `" "F=qvBsintheta`
`therefore" "[B]=[(F)/(qv)]=(["MLT"^(-2)])/(["AT"]["LT"^(-1)])=["MT"^(-2)"A"^(-1)]`
