The wavelength associated with a golf ball weighing 200 g and moving at a speed of `5 m//h` is of the order

Options

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

Answer

A

Explanation

According to de-Broglic's equation
`lamda=(h)/(p)=(h)/(mv)`
Given, `h=6.6xx10^(-34) Js, m=200xx10^(-3) kg`
`v=(5)/(60xx60) m//s`
`lamda=(6.6xx10^(-34))/(200xx10^(-3)xx5//(60xx60))=2.38xx10^(-10)m`
