A particle having a mass of \( 1 \mathrm{mg} \) has a velocity \( 1 \mathrm{Km} / \mathrm{sec} \).
Calculate the wavelength of the particle:
a. \( 6.626 \times 10^{-28} \mathrm{~cm} \)
b. \( 6.626 \times 10^{-29} \mathrm{~cm} \)
c. \( 6.626 \times 10^{-30} \mathrm{~cm} \)
d. \( 6.626 \times 10^{-31} \mathrm{~cm} \)
