Question

When an electric charge q is kept at rest in a magnetic field, the lorentz force is
A) Zero
B) positive
C) negative


​

Answer 1

Answer:

When an electric charge q is kept at rest in a magnetic field, no force acts on it. At the same time, if the charge moves in the magnetic field, it experiences a force. LORENTZ FORCE. When an electric charge q is kept at rest in a magnetic field, no force acts

Answer 2

Answer:

Electromagnetic force is the force on charged particle due to both electric field and magnetic field. Also, the electric force can be experienced by charges at rest. Magnetic force can be experienced by charges in motion. Hence, if a charged particle kept at rest experiences an electromagnetic force, the electric field must not be zero and the magnetic field may or may not be zero.
