According to the universal law of gravitation , the gravitational force of attraction between two masses separated by a certain distance is directly proportional to the product of their masses and inversely proportional to the square of the distance between the masses.
If m1 and m2 are the masses separated by a distance r then,
F= G m¹ x m²/r²
Here G is called the Universal gravitational constant. Its value is 6.67 × 10-11 Nm2kg-2
