Calculate the force of gravitation between two objects of masses 50 kg and 120 kg kept at 10 m from one another. (Gravitational constant G = 6.7 x 10-11 Nm2 kg-2).
Given:
The masses of two objects, m1 = 50 kg and m2 = 120 kg.
The distance ‘R’ between the two bodies = 10 m.
The gravitational constant (G) = 6.7 x 10-11 Nm2 kg-2.
Required to find:
The force of gravitation between the two objects.
Solution:
The force of gravitation (F) between two objects is given by .
By substituting the given values in the above equation, we get
Therefore, the force of gravitation between the two objects is 4.02 x 10-9 N.
