Moving Charges and Magnetism

Question:

Two charges A and B are present in electric and magnetic field. Charge A is moving with twice the velocity of charge B and charge B is kept at rest. Charge B is twice the charge A. What is the Lorentz force experienced by charge A and charge B respectively?

Options:

F, 2F

F, 3F

F, F

0, F

Correct Answer:

F, 2F

Explanation:

For A and B, v = 0

FA = qE = F ; FB = 2qE = 2F
