Question

A magnetic field directed in north direction acts on an electron moving in east direction. The magnetic force on the electron will actImmersive Reader
(a) vertically upwards.
(b) towards east.
(c) vertically downwards.
(d) towards north.

Answer 1

Answer:

ANSWER IS (B).........

Answer 2

The magnetic force on the electron will act Immersive Reader  vertically downwards.

• The magnetic force on a moving charged particle, such as an electron, is given by the cross product of the velocity of the particle and the magnetic field. In this case, the magnetic field is directed north, and the electron is moving east.
• The cross product of these two vectors will produce a force that is perpendicular to both the magnetic field and the velocity of the electron. Since the magnetic field is directed north, and the electron is moving east, the force will be directed vertically downwards.
• This is because the cross product of two vectors follows the right-hand rule, which states that the force will be directed in the direction that the thumb of the right hand points when the fingers are curled from the first vector to the second vector.
