Question: A charged particle moves in a magnetic field B with a velocity v. What is the expression for the magnetic force acting on the particle?

Options:

  1. qvB
  2. qvBsinθ
  3. qvBcosθ
  4. qB

Correct Answer: qvBsinθ

Solution: 

The magnetic force acting on a charged particle moving in a magnetic field is given by F = qvBsinθ, where θ is the angle between the velocity and the magnetic field.

Questions & Step-by-Step Solutions

A charged particle moves in a magnetic field B with a velocity v. What is the expression for the magnetic force acting on the particle?
  • Step 1: Identify the charged particle that is moving.
  • Step 2: Determine the velocity (v) of the charged particle.
  • Step 3: Identify the magnetic field (B) in which the particle is moving.
  • Step 4: Find the angle (θ) between the direction of the velocity and the direction of the magnetic field.
  • Step 5: Use the formula F = qvBsinθ to calculate the magnetic force (F) acting on the particle, where q is the charge of the particle.
  • Magnetic Force on a Charged Particle – The magnetic force experienced by a charged particle moving in a magnetic field is determined by the charge of the particle, its velocity, the strength of the magnetic field, and the angle between the velocity and the magnetic field.
