Question

Q.The approximate wavelength associated with a gold ball ring 200g and moving at velocity of 5 m/hr what is of the Order of
A. 10^-1m
B. 10^-20m
C. 10^-30m
D. 10^-40m​

Answer 1

Wavelength=h/mv,

                     =6.6*10-34 j-s/ 200*10-3kg*5/3600

                     =3.3*10-31*36/5

                     =118.8*10-31/5

                     =23*10-31

                    =2.3*10-30

                    =10-30 (ans)
