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, 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

A proton and an alpha particle, both are moving with same initial velocity, perpendicular to uniform magnetic field of 1 T. Find the ratio of radii of circles described by the alpha particle and the proton.

A deuteron and an alpha particle having same momentum are in turn allowed to pass through a magnetic field B, acting normal to the direction of motion of the particles. Calculate the ratio of the radii of the circular paths described by them.
