In an atom, an electron is moving with a speed
\( \mathrm{P} \)
\( 600 \mathrm{~m} / \mathrm{s} \) with an accuracy of \( 0.005 \% \). Certainty with
W
which the position of the electron can be located is (h \( =6.6 \times 10^{-34} \mathrm{~kg} \mathrm{~m}^{2} \mathrm{~s}^{-1} \), mass of electron, \( \left.\mathrm{e}_{\mathrm{m}}=9.1 \times 10^{-31} \mathrm{~kg}\right) \)
(1) \( 1.52 \times 10^{-4} \mathrm{~m} \)
(2) \( 5.10 \times 10^{-3} \mathrm{~m} \)
(3) \( 1.92 \times 10^{-3} \mathrm{~m} \)
(4) \( 3.84 \times 10^{-3} \mathrm{~m} \)
