What is de-Broglie wavelength of a 0.2 kg ball moving with speed of 30 `ms^(-1)` ?

Explanation

To find the de-Broglie wavelength of a 0.2 kg ball moving with a speed of 30 m/s, we can use the de-Broglie wavelength formula:

\[ \lambda = \frac{h}{p} \]

where:
- \(\lambda\) is the de-Broglie wavelength,
