Options

• Option A

  the electron will be accelerated along the axis.

• Option B

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

• Option C

  the electron path will be circular about the axis.

• Option D

  the electron will experience a force at 45° to the axis and execute a helical path.
