A beam of mixture of `alpha` particle and protons are accelerted through same potential difference before entering into the magnetic field of strength B. if `r_1=5` cm then `r_2` is

A proton and an alpha -particle are accelerated through same potential difference. Find the ratio of their de-Brogile wavelength.

If a proton, deuteron, and alpha particle on being accelerated by the same potential difference enters perpendicular to the magnetic field, then the ratio of their kinetic energies is

The ratio of deBroglie wavelegth of a proton and an a-particle accelerated through the same potential difference is-

A proton and an alpha particle accelerated through the same potential difference enter a region of uniform magnetic field normally if the radius of the proton orbit is 10 cm ten radius of alpha particle is

A proton, a deuteron and an alpha particle are accelerated through same potential difference and then they enter a normal uniform magnetic field, the ratio of their kinetic energies will be

A proton, a deutron and an alpha particle, after being accelerated through the same potential difference enter a region of uniform magnetic field vecB , in a direction perpendicular to vecB . Find the ratio of their kinetic energies. If the radius of proton's circular path is 7cm , what will be the radii of the paths of deutron and alpha particle?
