Question
II ONLY NEED PART 2
The speed of a 57.8 g bullet and the speed of an electron are measured to be the same, namely 264.2 m/s with an uncertainty of 0.028%. Within what fundamental accuracy could you locate the position of the bullet, if the position is measured simultaneously with the speed in the same experiment? 1.23 times l0-32 m Your receipt no. is 155-3174 Previous Tries And, within what fundamental accuracy could you locate the position of the electron, if the position is measured simultaneously with the speed in the same experiment? You must use the Heisenberg Uncertainty relationship Be careful with units.
Explanation / Answer
uncertainity principle is:
h/2pi = delta(x) * delta(p)
where h is plank constant
m and p is uncertanity is mass and p is momentum
for electron uncertainity in position will be
1.05 *10^-34 = delta(x) * 9.31 *10^-31 * 264.2
delta(x) = 4.26 * 10^-7
