An electron of charge 'e' and mass "m" describes a circular path of radius when it is projected with a velocity 'v' perpendicular to a uniform magnetic field of induction 'B'. An expression for its frequency of revolution is

Which particle will have minimum frequency of revolution when projected with the same velocity perpendicular to a magnetic field ?

A particle carrying a charge moves perpendicular to a uniform magnetic field of induction B with a momentum p then the radius of the circular path is

Which of the follwing particles will have minimum frequency of revolution when projected with the same velocity perpendicular to a magnetic field?

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

A particle of mass M and charge Q moving with velocity v describes a circular path of radius R when subjected to a uniform transverse magnetic field of induction B. The work done by the field when the particle completes one full circle is :

A particle is projected in a plane perpendicular to a uniform magnetic field. The area bounded by the path described by the particle is proportional to
