Question

A uniform electric field and a uniform magnetic field acting along the same direction in a certain region. If an electron is projected along the direction of the fields with a certain velocity, then, it will turn towards left of direction of motion., it will turn towards right of direction of motion., its velocity will increase., its velocity will decrease.

MARKS App · Accepted Answer

The magnetic field will not apply any force on the electron. On the other hand, the electric field will apply a force on the electron in opposite direction of the motion. As a result, the velocity of the electron will decrease.
