Answer 2

Answer:

Explanation:

Correct option is

D

10  

−30

m

According to de Broglie's equation  

λ=  

mv

h

​

 

where, λ= de-Broglie wavelength

h=6.626×10  

−34

Js=Planck's constant

m=mass of object=200 g= 0.2 kg and v= velocity=5m/h=5/3600 m/s

upon substitution we get:

λ=  

0.2×5

6.626×10  

−34

×3600

​

 

λ=2.385×10  

−30

m
