The associate wavelength of a particle with mass 1 gram and velocity 100 m/s is .........

Options

A. `6.63 xx10^(-35)` m
B. `6.63 xx10^(-36)` m
C. `6.626 xx10^(-33)` m
D. `6.626 xx10^(-34)` m

Answer

C

Explanation

`6.626 xx10^(-33)` m
m=1 gram =`1.0 xx10A^(-23)` kg
wavelength =`lambda=(?)`
`h=6.262 xx10(-34)` js
`lambda=(h )/(p)=(h)/(mv)=(6.626xx10A^(-34) js)/(1.0xx10A^(-3)kg xx100 ms^(-1))`
`=6.626xx10^(-33)` m
