Question

Because of electrons high speed, which of its properties cannot simultaneously be measured with certainty?

A. Position and charge
B. Position and momentum
C. Direction and charge
D. Charge and momentum

Answer 1

Position and momentum

Step-by-step explanation:

According to Heisenberg uncertainty principle, it is not possible to find the position and momentum of an electron simultaneously. Mathematically, it can be written as :

`\Delta x.\Delta p\geq (h)/(4\pi)`

Where

`\Delta x` is uncertainty in position

`\Delta p` is uncertainty in momentum

The above equation shows that if we know the position of an electron accurately, then its momentum cannot be known accurately and vice versa.

Hence, the correct option is (b) "Position and momentum".

Answer 2

Option B - Position and Momentum.

Explanation

This is because the electrons do not have an exact position and direction of motion at the same time as the momentum of an atom's section called electron is directly proportional to its velocity. This is happening while the state is based on its particle location in its wave properties. There are limits to the degree to which both the position and momentum of a particle can even be known due to the fact that electrons cannot exhibit both their wave and particle properties at the same time with their surroundings.
