A charged particle of mass m and charge q moves with a constant velocity v = a i along the positive x-direction. It enters a region of magnetic field which is directed towards positive z-direction, from x = l, which is given by B = b k and moves in a circular path.
Consider the following statements about the motion of the particle:
- Force will always be perpendicular to the velocity.
- The magnitude of the velocity remains constant.
- Velocity vector and magnetic field vector remain perpendicular to each other during the motion.
- KE of the particle remains constant.
Which of the following is true ?
