Download Solution PDFCONCEPT:
- Newton's law of gravitation: The gravitational force between two objects is directly proportional to the product of masses of the objects and inversely proportional to the distance between two mass.
i.e.,
whereas according to classical mechanics force acting on the particle is given as
Force (F) = mass (m) × acceleration (a)
Where, F = gravitational force, M = mass of a heavier object, m = mass of a lighter object, R = distance between two masses
EXPLANATION:
Now using the above equation, we can say that
The SI unit of force is the Newton (N).
The SI unit of distance (R) is meter (m) and the SI unit of mass is kg.
The SI unit of G = N m2/kg2
So option 3 is correct.
