UHow would the uncertainty in the momentum of the electron change if the electron were allowed

The position along the x axis of an electron is known to be between 0.31 nm and + 0.31 nm. How would the uncertainty in the momentum of the electron change if the electron were allowed to be between -0.62 nm and +0.62 nm? a) The uncertainty in the momentum would be twice its previous value. b) The uncertainty in the momentum would be half of its previous value. c) The uncertainty in the momentum would not be affected by this change. d) The uncertainty in the momentum would be four times its previous value. e) The uncertainty in the momentum would be one fourth its previous value.
