Question

Calculate the force of gravitation between two objects of masses 50 kg and 120 kg respectively kept at a distance of 10 m from one another (Gravitational constant, G = 6.7 × 10 ^ -11 Nm2 /kg^2).​

Answer 1

Solution :-

M¹ = 50 kg

M² = 120 kg

Distance ( r ) = 10 m

Force of gravitation = (G M¹ M²) / r²

F = (6.7 x 10-¹¹ ) (50 x 120) / 10²

So, F = 4.02 x 10 ^ ( -9 ) N

Answer 2

Answer:

40.2 ×10^-10

Explanation:

F=GMm / r^2

F = 6.7 ×10^-11 ×50×120/100

F = 40.2 ×10^-10
