Question

In the given figure, the electron enters into the magnetic field. It deflects in x direction .
Two parallel beams of electrons moving in the same direction produce a mutual force

• A. + ve X direction
• B. - ve X direction
• C. + ve Y direction
• D. - ve Y direction

Answer 1

The correct option is A + ve X direction

The direction of the force on a moving charge depends on the direction of its velocity. The magnetic force acting on a moving charged particle is the cross product of the velocity and the magnetic field
