On earth the weight of a body of mass 1.0 kg is 10 N. What will be the weight of a boy of mass 37 kg in kgf

Explanation

To find the weight of a boy with a mass of 37 kg in kgf (kilogram-force), we can follow these steps:

### Step 1: Understand the relationship between mass and weight
Weight (W) is the force exerted by gravity on an object and is calculated using the formula:
\[ W = m \times g \]
where:
- \( W \) is the weight in Newtons (N),
- \( m \) is the mass in kilograms (kg),
