Answer:
Use Heisenberg's uncertainty principle.
For example [Δx=
4πmΔv
h
]
Here, Δx is the uncertainty in the position.
Δv is the uncertainty in velocity
m is the mass of Particle.
Given,m=40g=0.04kg
Δv=2%ofv=2×
100
45
=0.9m/s
h=6.626×10
−34
J.s
Now,Δx=
(4×3.14×0.04×0.9)
6.626×10
−34
=1.4654×10
−33
m
So, the correct option is C
