A particle is moving three times as fast as an electron. The ratio of the de Broglie wavelength of the particle to that of the electron is 1.813 × 10–4. Calculate the particle’s mass and identify the particle.
Broglie expression is given by
m is the mass
h is he planks constant
v is velocity
is wavelength
(4)/(1) =>
of proton is
of neutron is
From the above the particle must be neutron.
