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:
- \(4.8 \times 10^{-27} \mathrm{~kg}\)
- \(1.2 \times 10^{-21} \mathrm{~kg}\)
- \(9.1 \times 10^{-31} \mathrm{~kg}\)
- \(9.7 \times 10^{-21} \mathrm{~kg}\)
Answer
(D) 9.7 10^ -21 ~kg
