The correct option is D infinite
Heisenberg's uncertainty principle states that it is impossible to determine both the position and the momentum of an electron inside an atom simultaneously.
Mathematically, it is derived that the product of uncertainties in position and momentum is greater than or equal to a constant h4π. The equation for that is:
Δx = Uncertainty in position
Δp = Uncertainty in momentum
h = Planck's constant
If the uncertainty in position, Δx = 0 then,
Δp = ∞
(since, dividing any finite number by zero gives infinity)
therefore, uncertainty in momentum, Δp = ∞.
