Pull of earth on a mass of 20 kg at surface of earth is: C) 20 N A) 196 N B) 1960 N D) 19.6 N

Explanation:

The pull of Earth on a mass of 20 kg at the surface of Earth can be calculated using the formula for gravitational force:

Force = mass × acceleration due to gravity

The acceleration due to gravity on the surface of Earth is approximately 9.8 m/s².

Let's calculate the force:

Force = 20 kg × 9.8 m/s² ≈ 196 N

So, the correct answer is:

B) 196 N
