(B) According to de-Broglie's equation,$\lambda = \frac{h}{mv}$.Given:$h = 6.6 \times 10^{-34} \ Js$$m = 9.0 \times 10^{-31} \ kg$$v = 2.2 \times 10^6 \ ms^{-1}$Substituting the values:$\lambda = \frac{6.6 \times 10^{-34}}{9.0 \times 10^{-31} \times 2.2 \times 10^6}$$\lambda = \frac{6.6}{19.8} \times 10^{-34+31-6} \ m$$\lambda = 0.333 \times 10^{-9} \ m$Since $1 \ nm = 10^{-9} \ m$,the wavelength is $0.33 \ nm$.
