Show that the radius of a charged particle entering perpendicularly in a magnetic field is directly proportional to its momentum.

If a charged particle enters perpendicular in the uniform magnetic field then

When a charged particle enters a uniform magnetic field its kinetic energy

Magnetic force acting on the charged particle projected perpendicular to magnetic field is proportional to v^(n) . Where v is the speed. Find n

Magnetic force acting on the charged particle projected perpendicular to magnetic field is proportional to r^(n) , where r is radius of circular path. Find n

A charged particle enters a uniform magnetic field perpendicular to it. The magnetic field

A charged particle of charge q and mass m enters perpendiculalry in a magnetic field B. Kinetic energy of particle is E, then frequency of rotation is

A charged particle is moved along a magnetic field line. The magnetic force on the particle is
