kinetic energy of the charged particle does not change

B

the charge of the particle remains same

C

the magnetic force is perpendicular to velocity of the particle

D

the magentic force is parallel to magnetic field

Text Solution

Verified by Experts

The correct Answer is:

The energy of a charged particle moving in uniform magnetic field does not change-Explain.

Write the expression for the magnetic force vecF acting on a charged particle q moving with vec upsilon in the presence of the magnetic field vec B in a vector form. Show that no work is done and no charge in the magnitude of the velocity of the particle is produced by this force. Hence define the unit of magnetic field.

Assertion: The energy of charged particle moving in uniform magnetic field does not change. Reason: Work done by magnetic field on the charge is zero.
