PhysicsMoving Charges and MagnetismMHT CET 2026

A charged particle is moving in a uniform magnetic field in a circular path of radius 'R'. When the energy' of the particle becomes 3 times the original, the new radius will be

Answer: (C)

Solution

In a magnetic field the magnetic force provides the centripetal force: , so . With kinetic energy we get , so . If the energy becomes 3
