A particle is moving 5 times as fast as an electron. The ratio of the de-Broglie wavelength of the particle to that of the electron is \( 1.878 \times 10^{-4} \). The mass of the particle is close to
(a) \( 4.8 \times 10^{-27} \mathrm{~kg} \)
(b) \( 9.1 \times 10^{-31} \mathrm{~kg} \)
(c) \( 9.7 \times 10^{-28} \mathrm{~kg} \)
(d) \( 1.2 \times 10^{-28} \mathrm{~kg} \)
