Questions & Step-by-Step Solutions
The force on a charged particle moving in a magnetic field is maximum when the angle between the velocity and the magnetic field is: (2021)
Step 1: Understand that a charged particle can experience a force when it moves through a magnetic field.
Step 2: Know that the force on the charged particle depends on the angle between its velocity and the direction of the magnetic field.
Step 3: Remember that the force is calculated using the formula F = q(v × B), where F is the force, q is the charge, v is the velocity, and B is the magnetic field.
Step 4: Realize that the force is maximum when the sine of the angle between the velocity and the magnetic field is maximum.
Step 5: The sine of an angle is maximum at 90 degrees, which means the angle between the velocity and the magnetic field should be 90 degrees for maximum force.
