A proton and an`alpha`-particles enters in a uniform magnetic field with same velocity, then ratio of the radii of path describe by them

A protn and an alpha particle enter into a uniform magnetic field with the same velocity. The period of rotation of the alpha particle will be

A proton , a deuteron and an alpha -particle enter a magnetic field perpendicular to field with same velocity. What is the ratio of the radii of circular paths ?

A proton and an a-particle enter in a uniform magnetic field perpendicularly with same speed. The will b ratio of time periods of both particle (T_(p)/(T_(alpha)) will be

A proton and an alpha- particle enter a uniform magnetic field at right angles to the field with same speed. The ratio of the periods of alpha- particle and proton is

A neutron, a proton, an electron and an alpha- particle enter a region of uniform magnetic field with equal velocities. The magnetic field is perpendicular to the paper and directed into it. The tracks of particles are labeled in Fig. 1.132. The neutron follows the track

A proton and an alpha- particle enter a uniform magnetic field moving with the same speed. If the proton takes 25 mu s to make 5 revolutions, then the periodic time for the alpha- particle would be
