Two particles A and B of masses ma and mu respectively and having the same charge are moving in a plane. A uniform magnetic field exists perpendicular to this plane. The speeds of the particles are vA and vu respectively and trajectories are as shown the figure. Then
Correct answer: B. MA VA > MB VB
- A. MA VA < MB VB
- B. MA VA > MB VB
- C. MA<MB and VA<VB
- D. MA=MB and VA=VB
Explanation
When a charged particle is moving at right angle to the magnetic field, then a force acts on it which behaves as a centripetal force and moves the particle in circular path.Explanation is given below:

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
