Q. 104.0( 2 Votes )

Two particles A<s A. their momenta are the same.

B. their energies are the same.

C. energy of A1 is less than the energy of A2.

D. energy of A1 is more than the energy of A2.

Answer :

We know the de Broglie wavelength of a particle is given by,

where h is the Planck’s constant, m is the mass and v is the velocity

where p=mv.

Since h is a constant and the particles have the same de Broglie wavelengths, their momenta are the same.

The kinetic energy of a particle with de Broglie wavelength is given by,

Hence, their energies are different.

m1 > m2

Hence, K2 > K1
