Write an expression in a vector form for the Lorentz magnetic force `vecF` on a charge Q moving with velocity `vecV` in a magnetic field `vecB`. What is the direction of the magnetic force?

A

qVB

B

`(BV)/(q)`

C

`(qV)/(B)`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
D
`F = qvB sin theta =qvB sin 0^(@)=0`
In this case, `theta= 0^(@), as vec v || vecB`
