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

A

`10^(-15) m`

B

`10^(-20)m`

C

`10^(-35)m`

D

`10^(-25)m`

Text Solution

Verified by Experts

The correct Answer is:
C
`m = 200 g = 200 xx 10^(-3) kg =2 xx 10^(-1) kg`
`v = 5m h^(-1) = (5)/(3600) ms^(-1) = 1.39 xx 10^(-3) ms^(-1)`
`h = 6.625 xx 10^(-34) Js`
`lambda = (h)/(mv) =(6.625 xx 10^(-34))/((2 xx 10^(-1)) xx (1.39 xx 10^(-3)))`
`1= 2.38 xx 10^(-30)m`
