JEE MainPhysicsMagneticsMCQ+4 / −1
An electron is projected with uniform velocity along the axis inside a current carrying long solenoid. Then :
  1. A
    the electron will experience a force at 45∘45^{\circ}45∘ to the axis and execute a helical path.
  2. B
    the electron will be accelerated along the axis.
  3. C
    the electron path will be circular about the axis.
  4. D
    the electron will continue to move with uniform velocity along the axis of the solenoid.
