### Post Module Calculation

I am wondering how I would solve for delta x in this problem. I approached it by first finding out delta p by doing mass times velocity which was 3 x 10^8 x 1/100. Then I plugged in delta p into Heisenberg's Equation to get delta x. Is this right? I did not get an answer that matched any of the choices, so I am just wondering if I did the problem wrong or if I just messed up a number somewhere along the way.

Calculate the uncertainty (indeterminacy) in position of an electron if its uncertainty in speed is one hundredth the speed of light.

Use the formula (h/4pi x delta p) and plug in all the values after solving for delta x.

I think the answer is Delta x >= 2 x 10^11 m

Correction 2 x 10^-11 m
