Question

Calculate the gravitational force of attraction between two bodies of masses 8 kg and 32 kg separated by a distance 16 m ​

Answer 1

Given:-

→ Mass of the 1st body = 8kg

→ Mass of the 2nd body = 32kg

→ Distance between the bodies = 16m

To find:-

→ Gravitational force of attraction

between the bodies.

Solution:-

• Value of G = 6.67×10⁻¹¹ Nm²/kg²

According to Newton's Universal Law Of Gravitation, we know that :-

F = GMm/r²

Where:-

• F is the gravitational force of attraction.

• G is Universal Gravitational Constant.

• M is mass of the 1st body.

• m is mass of the 2nd body.

• r is distance between the bodies.

By substituting the values in the above formula, we get :-

=> F = 6.67×10⁻¹¹×8×32/(16)²

=> F = 6.67×10⁻¹¹×256/256

=> F = 6.67×10⁻¹¹ N

Thus, gravitational force of attraction between the bodies is 6.67×10⁻¹¹ N .
