Options:
  • A the electron will continue to move with uniform velocity along the axis of the solenoid.
  • B the electron will be accelerated along the axis.
  • 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.

The correct answer is: the electron will continue to move with uniform velocity along the axis of the solenoid.

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