Question

Law of gravitation gives the gravitational force between

• A. the earth and a point mass only
• B. the earth and Sun only
• C. any two bodies having some mass
• D. two charged bodies only

Answer 1

The correct option is C

any two bodies having some mass

Universal law of gravitation:

1. The universal law of gravitation states that the attracting force between two objects is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.
2. Mathematically: $F\propto \frac{Mm}{d^2}=\frac{GMm}{d^2}$ Where $F$= force, $M$= mass of the first object, $m$=m ass of the second object, $d$= distance between them, $G$= universal gravitational constant.
3. The universal law of gravitation gives the gravitational force between any two objects having some mass.
4. It is evident from the formula that $F\propto Mm$, simply any type of two masses.

Hence, the correct option is option C.
