The wavelength associtated with a golf hall weight `200 g` and moving at a speed of `5 m h^(-1)` is of the order

Options

A. `10^(-10)m`
B. `10^(-20)m`
C. `10^(-30)m`
D. `10^(-40)m`

Answer

C

Explanation

The de Broglie wavelength is
`lambda= (h)/(mv) = ((6.26 xx 10^(-34) J s))/((0.200 kg){5m//(60 xx 60 s))}`
`= 2.4 xx 10^(-30)m`
