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

Position and momentum

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 :

Where

is uncertainty in position

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".

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).
