Question

Q4. Calculate the force of gravitation between a man weighing 60 kg and a boy weighing 20
kg standing 2 metres apart.​

Answer 1

Answer:

8.04 × 10-⁸ N.

Step-by-step explanation:

Mass of the man (m₁) = 80 kg

Mass of the boy (m₂) = 60 kg

Distance between the man and the boy

(d) = 2m

Gravitational constant (G) = 6.7 × 10-¹¹ N m²/kg²

The force exerted by the man on the boy is given by the formula for Newton's Universal law of gravitation, i.e.

Putting the given value in the above formula, we get

Thus, the gravitation force exerted by the man on the boy is 8.04 × 10-⁸ N.

This is an extremely small force.
