Physics Magnetism and Matter JEE Main 2023 - ( Magnetic Effects of Current ) MCQ (Single Correct)

An electron is moving along the positive x-axis. If uniform magnetic field is applied parallel to the negative z-axis, then

The electron will experience magnetic force along positive y-axis A and E only

The electron will experience magnetic force along negative y-axis C and D only

The electron will not experience any force in magnetic field B and E only

The electron will continue to move along the positive x-axis (E) The electron will move along circular path in magnetic field Choose the correct answer from the option given below: B and D only

Text Solution

Verified by Experts

The correct answer is:

The Lorentz force is given by

So,

is along - y axis

As the magnetic field is perpendicular to the velocity, motion would be circular.
