The velocity of `alpha`-particles is of the order of

Find the ratio of velocities of proton and alpha -particle if the de Broglie wavelengths of both the particles is same.

Find the ratio of velocities of proton and alpha -particle if the de Broglie wavelengths of both the particles is same.

An (alpha) -particle and a proton are both simultaneously projected in opposite direction into a region of constant magnetic field perpendicular to the direction of the field. After some time it is found that the velocity of the (alpha) -particle has changed in a direction by 45^(@) . Then at this time, the angle between velocity vectors of (alpha) -particle and proton is

A proton and alpha - particle are accelerated with same potential difference and they enter in the region of constant magnetic field B perpendicular to the velocity of particles. Find the ratio of radius of curvature of alpha - particle .

A nucleus moving with velocity bar(v) emits an alpha -particle. Let the velocities of the alpha -particle and the remaining nucleus be bar(v)_(1) and bar(v)_(2) and their masses be m_(1) and (m_2) then,
