Moving Charges and Magnetism

Question:

A charge moving with velocity v in X - direction is subjected to a field of magnetic induction in the negative X direction. As a result the charge will :

Options:

Remain unaffected

Start moving in YZ plane

Accelerates in X-axis

Rotate in circular path around X-axis

Correct Answer:

Remain unaffected

Explanation:

When magnetic field is in negative X direction

F = qVBsin180 = 0 (since sin180=0)

So, charge will not be affected.
