The heisenberg uncertainty principle states that the uncertainty in position multiplied by the uncertainty in momentum is greater than or equal to planck's constant divided by 4 pi.

So to answer this question, i need to make some assumptions.
00:23
A little bit more information would have been appreciated.

It says cricket ball, tennis ball, a proton, which has more uncertainty in velocity.
00:32
Well, to determine uncertainty and velocity, we need to assume that we know the mass exactly.
00:39
Then we can rewrite this equation as uncertainty in position, and momentum is mass times velocity.
00:51
But if we know the mass exactly, then there's uncertainty just in the velocity.

And that needs to be greater than or equal to planck's constant divided by 4 pi...
