Suppose the minimum uncertainty in the position of a
particleis equal to its de broglie wavelength. if the particle has
anaverage speed of 4.1 105
m/s, what is the minimum uncertainty in its speed?

The minimum uncertainty in its speed is greater than .

Explanation:

It is given that,

Speed of the particle,

We need to find the minimum uncertainty in its speed. It can be calculated using uncertainty principle as :

Since, p = mv

So, the minimum uncertainty in its speed is greater than . Hence, this is the required solution.
