b. position.
d. mass.
It is impossible to determine the exact position and momentum of electron simultaneously. Therefore, option B is the correct answer.
According to Heisenberg’s uncertainty principle,it is impossible to determine simultaneously, the exact position and momentum of an electron.
Mathematical expression
ΔX.ΔP ≥ h/4π
ΔX = uncertainty in position
ΔP = uncertainty in momentum
h = Plank’s constant
π= Pi
Thus, we can conclude its nearly impossible to determine electron’s exact position. Therefore, option B is the correct answer.
