Statement $$1$$: When a charging particle is fired in a magnetic field, the radius of its circular path is directly proportional to the kinetic energy of the particle.Statement $$2$$: The centripetal force on the test charge $$q0$$ is $$q0v2$$ B, where v is the velocity of a practical and B is the magnetic field in which the test charge in fired.

Question

Infinity Learn · Accepted Answer

If the path of the charged particle is circular, then radius of circular path is directly proportional to the speed and mass of the particle as $$r=$$ $$mvq0B$$∴   Centripetal  force  $$=$$ $$mv2r=q0vBAlso$$,   $$r=$$  $$2mK/qB$$
