Question

A golf ball mass of 45gm moving with velocity 50m per second.If accuracy in movement of velocity is 2percent.then find uncertainty principle​

Answer 1

Explanation:

Use Heisenberg's uncertainty principle.

For example [Δx=h/4πmΔv]

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% of v = 2×45/100 = 0.9m/s

h=6.626×10^-34J.s

Now, Δx = 6.626×10^−34/(4×3.14×0.04×0.9)

= 1.4654×10^−33m
