Problem

A charged particle is moving along positive

y

-axis in uniform electric and magnetic fields

\mathbf{E} = E_0 \hat{k}

and

\mathbf{B} = B_0 \hat{i}

Here,

E_0

and

B_0

are positive constants. Choose the correct options. a. - particle may be deflected towards positive

z

-axis b. - particle may be deflected towards negative

z

-axis c. - particle may pass undeflected d. - kinetic energy of particle may remain constant
