Heisenburgs Uncertainty Principle.
I keep getting the wrong answer and it is driving me crazy.

Using Heisenbergs uncertanty priciple, calculate the uncertanty in the position of a) A 1.50-mg mosquito moving at a speed of 1.40 m/s if the speed is known to within 0.01 m/s; and b) which I will try to figure out on my own if I fully understand this one.

The following post will show what I have done.

Heisenburgs Uncertainty Principle.

$$h= 6.626x10^{-34}$$
$$\Delta x = h/(4\pi *\Delta p)  $$
$$m = 1.5mg = 1.5 * 10^{6}$$
$$\Delta v = 1.4 m/s \pm0.01 m/s = 1.40*10^{-2}$$

I would assume, here that I have everything and it should just be plug and chug, however I am not getting the correct answer and do not know why.

1.5mg isn't 1.5x10^6 kg, it's 1.5x10^-6 kg. You're off by 12 orders of magnitude

anonymous · Answer

That was a typo, the magnitude is not what I am worried about, it is the actual value.
