A typical golf ball weighs

40.0 \mathrm{~g}

. If it is moving with a velocity of

20.0 \mathrm{~ms}^{-1}

, its de-Broglie wavelength is

View answer and explanation

Correct option: C

8.28 \times 10^{-25} \mathrm{~nm}

Option B (

8.28 \times 10^{-32} \mathrm{~nm}

) is correct because it is calculated using the de Broglie wavelength formula,

\lambda = \frac{h}{mv}

.
