Question

A uniform electric field and uniform magnetic field are acting along the same direction in a certain region. If an electron is projected in the region such that its velocity is pointed along the direction of fields, then the electron (A) will turn towards right of direction of motion (B) speed will decrease (C) speed will increase (D) will turn towards left direction of motion

Tardigrade Admin · Accepted Answer

When E, V and B are along same direction, then, magnetic force experienced by electron is zero while electric force is acting opposite to velocity of an electron, So the velocity of the electron will decrease.

Q. A uniform electric field and uniform magnetic field are acting along the same direction in a certain region. If an electron is projected in the region such that its velocity is pointed along the direction of fields, then the electron

will turn towards right of direction of motion

speed will decrease

speed will increase

will turn towards left direction of motion

When $E, V$ and $B$ are along same direction, then, magnetic force experienced by electron is zero while electric force is acting opposite to velocity of an electron, So the velocity of the electron will decrease.
