A charge q moves region in a electric field E and the magnetic field B both exist, then the force on its is:
(1.)q ( v × B )
(2.)q E + q ( v × B )
(3.)q B + q ( B × v )
(4.)q B + q ( B × v )

A

`q(vecVxxvecB)`

B

`qvecE+q(vecV+vecB)`

C

`qvecE+q(vecB+vecV)`

D

`qvecB+q(vecE+vecV)`

Text Solution

Verified by Experts

The correct Answer is:
B
Lorentz force `vecF_L=vecF_e+vecF_m`
`=qvecE+q(vecvxxvecB)`
