If an `alpha-` particle comes closure to a proton, it ………………. Proton.

The charge on alpha particle is ………The charge on proton

The charge on alpha particle is ………The charge on proton

A proton and and alpha - particle are accelerated through a potential difference of 100 V . The ratio of the wavelength with the proton to that associated to that associated with an alpha - particle is

A proton and an alpha - particle are accelerated through same potential difference. Then, the ratio of de-Broglie wavelength of proton and alpha-particle is

A proton and an alpha - particle are accelerated through same potential difference. Then, the ratio of de-Broglie wavelength of proton and alpha-particle is

A proton and an alpha - particle are accelerated through same potential difference. Then, the ratio of de-Broglie wavelength of proton and alpha -particle is

An alpha particle and a proton fall through the same potential difference. Find the ratio of their momentra if the mass of the alpha particle is four times that of the proton.
