The de-Broglie wavelength of a particle with mass `1 g` and velocity `100 m//sec` is.

Options

A. `6.63 xx10^(-33) m`
B. `6.63xx10^(-34) m`
C. `6.63xx10^(-35)m`
D. `6.65xx10^(-36)m`

Answer

A

Explanation

(a) `p=(h)/(lambda)`(de-Broglie equation)
`lambda=(h)/(mv) " " ` (`:' ` p=mv)
`h=6.625xx10^(-34)`
`~~6.63xx10^(-34) ` kg/s
`lambda=(6.63xx10^(-34) kg m^(2) //s)/(10^(-3)kgxx100m//s)`
`=6.63xx10^(-33)m`
