Question

Two bodies of mass 50 kg and 120 kg are kept at 10 m distant apart.Find the gravitational force between them. G =6.67*10-11 n-m2/kg2​

Answer 1

Answer:-

Given:

Mass of first object (M) = 50 kg

Mass of second Object (m) = 120 kg

Distance between them (r) = 10 m

G = 6.67 * 10⁻¹¹ N.m²/kg²

We know that,

Gravitational force (F) = GMm/r²

Hence,

⟶ F = (6.67) * (10)⁻¹¹ * (50) * (120) / (10)²

⟶ F = (6.67) * (10)⁻¹¹ * 60 * (10)² / (10)²

⟶ F = (6.67) * (10)⁻¹¹ * 6 * 10¹

Using a^m * a^n = a^(m + n) we get,

⟶ F = 40.02 * (10)⁻¹¹⁺¹

⟶ F = 40.02 * 10⁻¹⁰ N

Therefore, the gravitational force between them is 40.02 * 10⁻¹⁰ N.
