A charge is moving with velocity v, it enters a uniform magnetic field B. The direction of v is perpendicular to B. What is the path of the charge particle inside the magnetic field?
Correct answer: B. Circular
- A. Parabolic
- B. Circular
- C. Parallel to v
- D. Parallel to B
Explanation
The magnetic force will act perpendicular to velocity at every instant ,path will be circle. Due to change in direction momentum will change but the total energy will remain same.

About Charged Particle in a Magnetic Field
A charged particle moving through a magnetic field experiences the Lorentz force, which is perpendicular to both its velocity and the field. The motion may be circular or helical, with questions involving radius, angular frequency, time period, and work done. A stationary charge feels no magnetic force.
