Bihar Police Constable Model Paper 7

The correct answer is option 1) i.e. Law of Universal Gravitation

CONCEPT:

• Law of Universal Gravitation: It states that all objects attract each other with a force that is proportional to the masses of two objects and inversely proportional to the square of the distance that separates their centres.

It is given mathematically as follows:

F = $\frac{\mathit{G}{\mathit{m}}_1{\mathit{m}}_2}{{\mathit{R}}_2}$

Where ${\mathit{m}}_1$ and ${\mathit{m}}_2$ are the mass of two objects, G is the gravitational constant and R is the distance between their centres.

EXPLANATION:

• Every object in the universe attracts every other object with a force called gravitational force. Hence, the correct answer is the law of universal gravitation.
