If a particle moves in a circular path in clockwise direction after entering into a downward vertical magnetic field. The charge on the particle is-

A charged particle enters at 60^@ to the magnetic field: The path of the charged particle

A charged particle is moving on circular path with velocityv in a uniform magnetic field B, if the velocity of the charged particle is doubled and strength of magnetic field is halved, then radius becomes

A charged particle is moving on circular path with velocityv in a uniform magnetic field B, if the velocity of the charged particle is doubled and strength of magnetic field is halved, then radius becomes

Assertion: If a charged particle is moving on a circular path in a perpendicular magnetic field, the momentum of the particle is not changing. Reason: Velocity of the particle in not changing in the magnetic field.

A charged particles enters a magnetic field at an anle of 90^@ with magnetic field. The path of the particle will be:

A charged particle is moving in a circular path in uniform magnetic field. Match the following.

A charged particle is moving in a circular path in uniform magnetic field. Match the following.
