What is the importance of the universal law of Gravitation?

Content Curator

According to the Universal Law of Gravitation, every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them.

The importance of the Universal Law of Gravitation is as follows:

It explains the phenomenon of revolutions of heavenly bodies: All heavenly bodies or celestial bodies like planets and satellites move in an elliptical orbit due to gravitational force.
It tells us about the force that is responsible for binding us to the earth: The gravitational force of attraction between the earth and us helps to keep us on the ground. Since the mass of the earth is very large compared to us, so we are attracted to the earth.
It explains the formation of tidal waves: Ocean tides result from the rise and fall of water levels due to the gravitational force exerted by both the sun and moon.
A planet's orbit around the sun, a moon's orbit around the Earth, and an artificial satellite's orbit around the Earth are all explained by the law of gravitation.
Rainfall, snowfall, and the flow of water in rivers on the planet are also explained by the universal law of gravitation.

Four long straight thin wires are held vertically at the corners A, B, C and D of a square of side \( a \), kept on a table and carry equal current \( I \). The wire at A carries current in upward direction whereas the current in the remaining wires flows in downward direction. The net magnetic field at the centre of the square will have the magnitude:

\( \dfrac{\mu_0 I}{\pi a} \) and directed along OC
