4.Moving Charges and Magnetism
hard

An electron is projected with uniform velocity along the axis inside a current carrying long solenoid. Then :

A

 the electron will be accelerated along the axis.

B

the electron will continue to move with uniform velocity along the axis of the solenoid.

C

the electron path will be circular about the axis.

D

 the electron will experience a force at $45^{\circ}$ to the axis and execute a helical path.

Solution

Since $\vec{v} \| \vec{B}$ so force on electron due to magnetic field is zero. So it will move along axis with uniform velocity.
