The de Broglie wavelength associated with a particle of mass 10-6 kg m

1.	The de Broglie wavelength associated with a particle of mass 10-6 kg moving with a velocity of 10 m s-1 is ………..(A) 6.63 × 10-22m (B) 6.63 × 10-29m (C) 6.63 × 10-31m (D) 6.63 × 10-34m
Answer» Correct Option is : (B) \(6.63 \times 10^{-29} m\) \(\lambda = \frac{h}{p} = \frac{h}{mv}\) \(\lambda = \frac{6.63 \times 10^{-34} \ Js }{10^{-6} \times 10}\) \(\lambda = 6.63 \times 10^{-29} m\) Option : (B) 6.63 × 10^-29m

Answer»

Correct Option is : (B) \(6.63 \times 10^{-29} m\)

\(\lambda = \frac{h}{p} = \frac{h}{mv}\)

\(\lambda = \frac{6.63 \times 10^{-34} \ Js }{10^{-6} \times 10}\)

\(\lambda = 6.63 \times 10^{-29} m\)

Option : (B) 6.63 × 10^-29m
