Question

The speed of an electron is measured to be 5χ103 m/s to an accuracy of
0.003%. Find the uncertainty in determining position of this electron.

Answer 1

thus this is the answer hope it helps you

Answer 2

Answer:

Uncertainty in determining position of this electron is 0.015 m

Explanation:

From the above question,

They have given :

The speed of an electron is measured to be 5χ103 m/s to an accuracy of

0.003%.

The uncertainty of a measurement is equal to the accuracy of the measurement multiplied by the magnitude of the measurement, divided by 100. In this case, the accuracy of the measurement is 0.003% and the magnitude of the measurement is 5x103 m/s, so the uncertainty in the position of the electron is 0.015 m.

To find the uncertainty in determining position of this electron:

Uncertainty in position = (speed * uncertainty in speed) / 100

Uncertainty in position = (5 x 103 m/s * 0.003% ) / 100

Uncertainty in position = (5 x 103 m/s * 0.00003) / 100

Uncertainty in position = 0.015 m
