A beam of `alpha`- particles and of protons, of the same velocity v, enters a uniform magnetic field at right angles to the field lines. The aprticles describe

A proton and an alpha particle of the same velocity enter in turn a region of unifrom magnetic field acting a plane perpendicular to the magnetic field. Deduce the ratio of the radii of the circular paths described by the particles. Explain why kinetic energy of the particle after emerging from the magnetic field remains unaltered.

If electron and proton having same momenta enter normally to a magnetic field then

A particle of charge ‘q’moves with a velocity v at an angle ‘0’ to a magnetic field ‘B’. What is the force experienced by the particle ?

A charged particle moves with velocity vecv in a uniform magnetic field vecB . The magnetic force experienced by the particle is

An electron and a proton,moving parallel to each other in the same direction with equal momenta enter into a uniform magnetic field which is at right angles to their velocities.Trace their trajectories in the magnetic field.

An electron and a proton moving parallel to each other in the same direction with equal momenta enter into a unifrom magnetic field which is at right angles to their velocities. Trace their trajectories in the magnetic field?

An alpha-particle and a proton are moving in the plane of the paper in a region where there is a uniform magnetic field vecB directed normal to the plane of the paper. If the two particles have equal linear momenta, what will be the ratio of their trajectories in the field?

What will be the path of a charged particle moving along the direction of a uniform magnetic field?

A charged particle moves thorugh a uniform magnetic field perpendicular to its direction. Then
