Q.An electron is moving with a kinetic energy of $4.55 \times 10^{-25} \text{ J}$ . Its de-Broglie wavelength is: ( $h = 6.6 \times 10^{-34} \text{ J s}$ , $m_e = 9.1 \times 10^{-31} \text{ kg}$ )

7.2 \times 10^{-7} \text{ m}

7.2 \times 10^{-9} \text{ m}

3.3 \times 10^{-7} \text{ m}

6.6 \times 10^{-7} \text{ m}

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