A strong magnetic field is applied on a stationary electron, then

A

moves in the direction of the field.

B

remained stationary.

C

moves perpendicular to the direction of the field.

D

moves opposite to the direction of the field.

Text Solution

Verified by Experts

The correct Answer is:
B
As `vecF=vecq(vecv xx vecB)`
As the electron is stationary, `therefore` velocity `vecv=0`
`therefore" "vecF=0`. So, electron will remain stationary.

Assertion (A),If electrons travel undefeccted by the electric field E and magnetic field B then the velocity of electrons is given by V=e/b . Reason (R ) : When both electric and magnetic field are applied simultaneously on electron beam. If force due to electric field is equal and opposite to force due to magnetic field then they travel undeflected.
