Q.The uncertainty in position of an electron ( $m = 9.1 \times 10^{-31} \text{ kg}$ ) moving with a velocity $300 \text{ m/s}$ , accurate up to $0.001\%$ , will be: ( $h = 6.63 \times 10^{-34} \text{ J s}$ )

1.92 \times 10^{-2} \text{ m}

3.84 \times 10^{-2} \text{ m}

1.92 \times 10^{-5} \text{ m}

5.76 \times 10^{-2} \text{ m}

The correct solution involves applying the fundamental concept to derive the final value step by step...
