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

Options

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

Answer

C

Explanation

According to de Broglie's equation
`lambda=(h)/(m upsilon)=(6.626xx10^(-34)(kgm^(2)s^(-1)))/((0.200kg)xx((5)/(60xx60)ms^(-1)))`
`=(6.626xx60xx60xx10^(-34))/((0.200xx5))`
`=2.385xx10^(-30)m~~10^(-34)m`.
