A proton an an `alpha-`particle, moving with the same velocity, enter a uniform magnetic field, acting normal to the plane of their motion. The ratio of the radii of the circular paths descirbed by the proton and `alpha`-particle is

A proton and an alpha particle projected with same velocity in uniform transverse magnetic field then

A proton and an alpha particle projected with same velocity in uniform transverse magnetic field then

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.

A proton, a deuteron and an alpha -particle with the same KE enter a region of uniform magnetic field, moving at right angles to B. What is the ratio of the radii of their circular paths ?

A proton, a deuteron and an alpha -particle with the same KE enter a region of uniform magnetic field, moving at right angles to B. What is the ratio of the radii of their circular paths ?

An alpha particle and a proton travel with same velocity in a magnetic field perpendicular to the direction of their veloccites find the ratio of the radii of their circular path
