What does the "r" in the universal gravitation equation represent?Gravitational constantDifference in the mass of the two objectsDistance between the centers of the two objectsForce of attraction

According to the universal law of gravitation, the force between two particles or bodies isdirectly proportional to the product of their masses and inversely proportional to the square ofthe distance between these particles or bodies. Consider two bodies A and B having masses m1and m2 respectively. Let the distance between these bodies be R. The force of gravitationbetween these bodies is given byF ∝ m1m2 and F ∝ 1/R2F =G m1 m2/R2Where G is constant and is known as the “universal gravitational constant”.How does the force of gravitation between two objects change when the distance between themis reduced to half?a. The value of g on moon is …….. times that of earthb.If the moon attracts earth, why does the earth not move towards the moon?c.What is the importance of universal law of gravitation

According to the Law of Universal Gravitation, the gravitational attraction between two objects is proportional in which way?Inversely proportional to the product of their massDirectly proportional to the product of their massDirectly proportional to the square of the distance between their centersInversely proportional to the sum of their mass

According to the universal law of gravitation, gravitational force exerted on an object of mass m is given by:

gravitational force formula by mass and distance

Newton’s law of universal gravitation is represented by F = GmM r2 . where F is the magnitude of the gravitational force exerted by one small object on another, M and m are the masses of the objects, and r is a distance. Force has the SI units kg · m/s2. What is the SI units of the proportionality constant G? (a) kg · s2/m3 (b) m3/kg · s (c) m2/kg · s2 (d) kg2/m2 (e) m3/kg · s2 Q5: A solid piece of lead has a mass of 23.94 g and a volume of 2.10 cm3. From these data, what is the density of lead in SI units (in mega-gram per cubic meter)? (a) 1.14 M g/m3 (b) 1.14 × 104 M g/m3 (c) 11.4 M g/m3 3
