Question- Assertion: when direction of velocity of moving charges is perpendicular to the magnetic field it experiences a maximum force
Reason: force on moving charge does not depend on the direction of the magnetic field in which it moves

Answer 1

Answer:

3

Explanation:

the force depends on the diredtion of particle bcs if u see in the cartesian plane the i j k value differs the direction and a magnitude differs

Answer 2

The assertion is true but reason is false.

Option (3) is correct.

Explanation:

Assertion: When direction of velocity of moving charges is perpendicular to the magnetic field it experiences a maximum force .

Reason: Force on moving charge does not depend on the direction of the magnetic field in which it moves.

The assertion is true but reason is false.

It is because the force depends on the direction of particle because in the Cartesian plane the values of i , j and k vary with respect to the the direction and a magnitude of the particle.
