Question

Three charged particles, having charges (q₁ , q₂ , q₃) and masses (m₁ , m₂ , m₃), are accelerated (from rest) through potential V₁ , V₂ and V₃, respectively. Their associated deBroglie wavelengths are equal, respectively, to the wavelengths of photons, having energies E₁, E₂ and E₃. We would then have:

Answer 1

Correct option :  (3)

Explanation :

The kinetic energy, acquired by a particle of charge q, when accelerated (from rest), through a potential V, is K = qV

Also deBroglie wavelength, 

The wavelength (λ'), associated with a photon of energy E, is given by
