The measurement of the electron position is associated with an uncertainty in momentum, which is equal to 1×10−18 g cm s−11\times10^{-18}\ \text{g cm s}^{-1}. The uncertainty in electron velocity is (mass of an electron is 9×10−289\times10^{-28} g)

Multiple Choice Options

  • A 1×105 cm s−11\times10^5\ \text{cm s}^{-1}
  • B 1×1011 cm s−11\times10^{11}\ \text{cm s}^{-1}
  • C 1×109 cm s−11\times10^9\ \text{cm s}^{-1}
  • D 1×106 cm s−11\times10^6\ \text{cm s}^{-1}
