Question

An electron is travelling horizontallty towards east. A magnetic field in vertically downward (inside the plane of paper) direction exerts a force on the electron along
(A) East (B) West
(C) North (D) South

Answer 1

Explanation:

An electron is travelling horizontally towards east and a magnetic field in vertically downward direction.

we know, F =

-e(v × B)

where F is magnetic force vector, v is velocity vector { it shows direction of motion of charged particle} and B is magnetic field vector.

now, use flaming left hand rule, we get, direction of magnetic force vector is along south.

hence, force exerted on the electron along South.

Answer 2

Answer: heyyy~

South

Explanation:

Fleming's left-hand rule is used to determine the direction of the force. According to it, the force experienced will be in the south direction.
