Question

An electron moves in the negative x direction, through a uniform magnetic field in the negative y direction. The magnetic force on the electron is V A. In the negative z direction B. In the positive z direction C. In the negative y direction D. In the positive y direction Two charged particles M and N are projected with same velocity in a​

Answer 1

Answer:

As electron moving in positive x-direction, so the current is moving in negative x-direction ( the direction of your middle finger) and the magnetic field acts on positive Y-direction ( the direction of your index finger) then thumb will be in negative Z-direction which is the direction of force.
