\mathrm{Be}^{3+}

and a proton are accelerated by the same potential, their de-Broglie wavelengths have the ratio (assume mass of proton = mass of neutron) :

View answer and explanation

Correct option: D

1: 3 \sqrt{3}

Option D (

1: 3 \sqrt{3}

) is correct because the de Broglie wavelength is inversely proportional to the square root of the mass and charge, leading to the given ratio after calculation.
