a) State and explain Bohr's postulates of an atomic model.
b) i) Calculate the de-Broglie wavelength of a neutron having kinetic energy 150eV.
ii) A proton and an electron have same K.E. which one has greater de-Broglie wavelength?
[Given : Mass of neutron \( = 1.675 \times 10^{-27} \) kg, Planck's constant \( = 6.62 \times 10^{-34} \)JS]
