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

Options

A. `6.63 xx 10^(-33) m`
B. `6.63 xx 10^(-34) m`
C. `6.63 xx 10^(-35)m`
D. `6.65 xx 10^(-35) m`.

Answer

A

Explanation

`lambda =(h)/(mv) = (6.63 xx 10^(-34) kg m^(2)//s)/(10^(-3) kg xx 100 m//s)`
`= 6.63 xx 10^(-33)m`.
