A charge particle is moving along positive y-axis in uniform electric and magnetic fields
`E=E_0hatk`
and `B=B_0hati`
Here `E_0` and `B_0` are positive constants.choose the correct options.

A

particle may be deflected towards positive x-axis

B

particle may be deflected towards negative z-axis

C

particle may pass undeflected

D

kinetic energy of particle may remain constant

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
`F_m=q(vxxB)`
Depending on sign of `q,F_m` may be along positive `z`-axis or along negative z-axis.
`F_e=qE`
Again depending on the value of `q` it may be along positive `z`-axis alos. But `F_e` comes along positive `z` axis. So, it may also pass undeflected.
