Answer:
The kinetic energy of an electron is
Explanation:
Given that,
Distance = 0.1 nm
We need to calculate the momentum
Using uncertainty principle
Where, = change in momentum
= change in position
Put the value into the formula
We need to calculate the kinetic energy for an electron
Where, P = momentum
m = mass of electron
Put the value into the formula
Hence, The kinetic energy of an electron is
