Answer 1

The correct answer is F = G (M × m)/d²

Key Points

The formula for the force of attraction (F) between two objects of masses M and m which lie at a distance d from each other is given by Newton's Law of Universal Gravitation.
The formula is F = G (M × m) / d².
Here, G is the universal gravitation constant.
This law states that every point mass attracts every other point mass by a force acting along the line intersecting both points.
The force is directly proportional to the product of the two masses and inversely proportional to the square of the distance between the point masses.

Additional Information

Newton's Law of Universal Gravitation was formulated by Sir Isaac Newton in 1687.
The universal gravitation constant G is approximately equal to 6.674 × 10^-11 N(m/kg)².
This law helps explain the motion of planets, moons, and artificial satellites.
It is a cornerstone in the field of classical mechanics and has been confirmed by numerous experiments and observations.
