This is ur ans. hope it will help u
if u like my ans. plzzzz mark me as brainileast
The two objects of masses 20 kg and 50 kg are separated by distance 8 m
We know that , the gravitational force between two objects is given by
Two objects of masses 20kg and 50kg are placed at distance 8m.
We have to find the gravitational force between them
◈ As per newton's law of gravitation, force acts between two point masses is directly proportional to the product of their masses and inversely proportional to the square of distance between them.
፨ F ∝ m₁m₂ / r²
፨ F = G × m₁m₂ / r²
Where G denotes gravitational constant.
⇒ F = (6.67×10ˉ¹¹) × (20×50)/8²
⇒ F = 66.7 × 10ˉ¹¹ × 10² / 64
⇒ F = 1.04 × 10N
