Order of `q//m` ratio of proton, `alpha`-particle and electron is

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

e//m ratio of proton is greater than that of electron

e//m ratio of proton is greater than that of electron

Assertion An alpha- particle and a deuteron having same kinetic energy enter in a uniform magnetic field perpendicular to the field. Then, radius of circular path of alpha- particle will be more. Reason (q)/(m) ratio of an alpha- particle is more than the (q)/(m) ratio of a deuteron.

The ratio of the e/m values of a proton and an alpha -particle is:

What is the ratio of mass of an alpha -alpha particle and a proton ?

What is the ratio of mass of an alpha -alpha particle and a proton ?

if m_p and m_(alpha) are masses of proton and alpha- particles find ratio of momentum of a proton and an alpha- particle which are accelerated fromr est by a potential difference of 200 V.

if m_p and m_(alpha) are masses of proton and alpha- particles find ratio of momentum of a proton and an alpha- particle which are accelerated from rest by a potential difference of 200 V.
