A proton and a-particle are accelerated through different potentials V1 and V2 respectively so that they have the same de Broglie wavelengths. Find V1/V2.

Ans.

we found that the ratio of the potentials �1 to �2 required to accelerate a proton and an alpha particle, respectively, to the same de Broglie wavelength is:

�1�2=14

Therefore, the ratio of the potential required to accelerate the proton to the potential required to accelerate the alpha particle is 1:4.
