Options

  1. A2
  2. B2
  3. C4

Correct answer

A. 2

Step-by-step solution

de-Broglie wavelength ( ) of the particle in terms of kinetic energy K is given as = h 2 m K where, m is the mass of the particle and h is Planck's constant. Let at wavelength ^ , kinetic energy of particle becomes K^ = K 4 [from Eq. (i)]
