The radius of circular path of an electron when subjected to a perpendicular magnetic field is

What is the radius of the circular path of an electron moving at a speed of 3 x 10^7 m/s in a magnetic field of 6x 10^(-4) T perpendicular to it?

(A) : The trajectory of neutron when it is projected perpendicular to a magnetic field is a parabola . (R) : A moving charge entering parallel to the magnetic field lines moves in a circular path.

The radius of the circular path described by a charged particle in a magnetic field is directly proportional to the

The momentum of alpha -particles moving in a circular path of radius 10 cm in a perpendicular magnetic field of 0.05 tesla will be :

The momentum of alpha -particles moving in a circular path of radius 10 cm in a perpendicular magnetic field of 0.05 tesla will be :

If a charged particle is describing a circular path of radius r under the effect of perpendicular electric field, (i.e., motion of an electron around the nucleus of an atom) the force on the charged particle is……………..proportional to the …………..of radius of the circular path.

Electric charge Q having mass M moves on a circular path of radius R with velocity vecv , perpendicular to uniform magnetic field B. When a particle completes one revolution, work done by the field is _______
