What will be the de Broglie wavelength associated with a ball of mass 250 g moving with velocity of 150 km/h ?

Explanation

To find the de Broglie wavelength associated with a ball of mass 250 g moving with a velocity of 150 km/h, we will follow these steps:

### Step 1: Convert mass from grams to kilograms
The mass of the ball is given as 250 g. To convert this to kilograms, we use the conversion factor:
\[ \text{Mass in kg} = \text{Mass in g} \times \frac{1 \text{ kg}}{1000 \text{ g}} \]
So,
