Question

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

Answer 1

Correct Answer - 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.
