Question
A $0.66 \text{ kg}$ ball is moving with a speed of $100 \text{ m/s}$. The associated de-Broglie wavelength will be approximately:
Answer: B
💡 Solution & Explanation
Applying the de-Broglie equation: $\lambda = \frac{h}{mv} = \frac{6.6 \times 10^{-34}}{0.66 \times 100} = \frac{6.6 \times 10^{-34}}{66} = 1.0 \times 10^{-35} \text{ m}$.
