Question

calculate the force of gravitation between two objects of masses 80kg and 1200kg kept at a distance of 10m from each other.​

Answer 1

Correct question:-

Calculate the force of gravitation between two objects of masses 80kg and 1200kg kept at a distance of 10m from each other.

Given:-

•Mass of the first object(M)=1200kg

•Mass of the second object(m)=80kg

•Distance between them(r)=10m

To find:-

•Force of gravitaion between the two objects

Solution:-

•Value of G(Gravitational constant)=6.67×10^-11 Nm²/kg²

By Newton's Universal Law of Gravitation,we know that:-

=>F=GMm/r²

=>F=6.67×10^-11×1200×80/10×10

=>F=6.67×10^-11×120×8

=>F=6403.2×10^-11

=>F=6.4×10^-8 N

Thus gravitational force of attraction between the two objects is 6.4×10^-8 N
