Solution

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^-11Nm² 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 $F = \frac{G m_{1} m_{2}}{R^{2}}$ .
By substituting the given values in the above equation, we get
$F = \frac{(6.7 x 10^{- 11}) x (50) x (120)}{10^{2}} = \frac{40, 200 x 10^{- 11}}{100} = 4.02 x 10^{- 9} N$
Therefore, the force of gravitation between the two objects is 4.02 x 10^-9 N.
