A) Momentum,p = n*h/(2*pi*r_{n}) ; where h = Planck's constant ; r_{n} = radius of the shell = 0.53*n^{2} A^{0}
Thus, for n = 2, momentum = (2*6.63*10^{34})/(2*3.14*0.53*10^{10}*4) = 9.96*10^{25} kgms
B) de Broglies wavelength = h/p = (6.63*10^{34})/(9.96*10^{25}) = 6.657*10^{10} m = 0.666 nm
C) K.E = (1/2)*p^{2}/m = (1/2)*(9.96*10^{25})/9.1*10^{31} = 5.45*10^{19} J
D) Energy = 13.6/n^{2} eV
Thus, for n = 2 , E_{2} = 3.4 eV
for n = 3 , E_{3} = 1.51 eV
Thus, transition energy = 1.51 (3.4) = 1.89 eV = 3.024*10^{19} J
