A particle of mass m moves in circular orbits with potential energy V(r) = Fr, where F is a positive
constant and r is its distance from the origin. Its energies are calculated using the Bohr model. If the
radius of the particle’s orbit is denoted by R and its speed and energy are denoted by v and E,
respectively, then for the n

^{th}orbit (here h is the Planck’s constant)2

A free hydrogen atom after absorbing a photon of wavelength $$\lambda $$

_{a}gets excited from the state n = 1 to the state n = 4. Immediately after that the electron jumps to n = m state by emitting a photon of wavelength $$\lambda $$_{e}. Let the change in momentum of atom due to the absorption and the emission be $$\Delta {p_a}$$ and $$\Delta {p_e}$$, respectively. If $${{{\lambda _a}} \over {{\lambda _e}}} = {1 \over 5}$$, which of the option(s) is/are correct? [Use hc = 1242 eVnm; 1 nm = 10^{-9}m, h and c are Planck's constant and speed of light in vacuum, respectively]3
