The de-Broglie wavelength associated with a particle of mass `10^-6 kg` moving with a velocity of `10 ms^-1`, is

Options

A. `6.3 xx 10^(-22)` m
B. `6.63 xx 10^(-29)`m
C. `6.63 xx 10^(-31)m`
D. `6.63 xx 10^(-34)`m

Answer

B

Explanation

`lambda = (h)/(mv) = (6.63 xx 10^(-34))/(10^(-6) xx 10) = 6.63 xx 10^(-29) m`
