An observer is moving with constant velocity v towards right. Which of the following statement is correct with respect to observer.
Path of the charged particle will be straight line.
Magnetic force on the charged particle is zero.
Magnitude of magnetic force on charged particle is qvB initially.
Both (1) and (3)
Answer (3)
The charged particle is moving in straight line at speed v w.r.t the observer in backward direction.
