Answer:
Newton's Universal law of gravitation states: "Every body in this universe attracts each other body with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers."
Its SI unit is Nm^2/Kg^2
Explanation:
Universal law of gravitation states that every body in the universe attract each other with a force F which is
Mathematically ,
[tex]\tt \implies F \propto \frac{ m_{1}m_{2} }{ {(r)}^{2} } [/tex]
[tex] \tt \implies F = G \frac{ m_{1}m_{2} }{ {(r)}^{2} } [/tex]
Where , G is a constant of proportionality and is called universal gravitational constant
G = 6.67 × 10^(-11) N-m²/kg²
Universal gravitational constant is defined as the force of attraction between two bodies of unit mass are separated by unit distance
