A 200 g golf ball is moving with a speed of 5 m per hour. The associated wavelength is (`h=6.625xx10^(-34)` J -sec) of the order of

A

`10^(-10)` m

B

`10^(-20)` m

C

`10^(-30)` m

D

`10^(-40)` m

Text Solution

Verified by Experts

The correct Answer is:
C
`lambda=h/"mv"=(6.625xx10^(-34))/(0.2 kg xx (5)/(60xx60ms^(-1))) =10^(-30) m xx 2.4`
