A `200 g` cricket ball is thrown with a speed of `3.0 xx 10^3 cm sec^-1`. What will be its de Broglie's wavelength ?
`[h = 6.6 xx 10^-27 g cm^2 sec^-1]`.

Options

A. `1.1 xx 10^-32 cm`
B. `2.2 xx 10^-32 cm`
C. `0.55 xx 10^-32 cm`
D. `11.0 xx 10^-32 cm`

Answer

A

Explanation

(a) `lamda = (h)/(mv)`
=`(6.6 xx 10^-27)/(200 xx 3 xx 10^3)`
=`(6.6 xx 10^-32)/(6)`
`lamda = 1.1 xx 10^-32 cm`.
