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

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

The velocities of two alpha particles entering a uniform magnetic field are in the ratio 2:3. What is the ratio of the radii of their circular path.

A proton and an alpha particle enter the same magnetic field which is perpendicular to their velocity. If they have same kinetic energy then ratio of radii of their circular path is

A proton and an alpha particle enter the same magnetic field which is perpendicular to their velocity. If they have same kinetic energy then ratio of radii of their circular path is

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, 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 ?
