Give the applications of universal law gravitation.

उत्तर
Application of Newton’s law of gravitation are:
- Dimensions of the heavenly bodies can be measured using the gravitation law. Mass of the Earth, the radius of the Earth, acceleration due to gravity, etc., can be calculated with higher accuracy.
- Helps in discovering new stars and planets.
(Hi) Helps to explain germination of roots is due to the property of geotropism which is the property of a root responding to gravity. - One of the irregularities in the motion of stars is called ‘Wobble’ leads to the disturbance in the motion of a planet nearby. In this condition, the mass of the star can be calculated using the law of gravitation.
- Helps to predict the path of the astronomical bodies.

Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.
If you compare the gravitational force on the Earth due to the Sun to that due to the Moon, you would find that the Sun’s pull is greater than the Moon’s pull. (You can check this yourself using the data available in the succeeding exercises). However, the tidal effect of the Moon’s pull is greater than the tidal effect of Sun. Why?
State two applications of universal law of gravitation.
Universal law of gravitation states that every object exerts a gravitational force of attraction on every other object. If this is true, why don’t we notice such forces ? Why don’t the two objects in a room move towards each other due to this force ?
Two spherical balls of mass 10 kg each are placed 10 cm apart. Find the gravitational force of attraction between them.
Four particles of equal masses M move along a circle of radius R under the action of their mutual gravitational attraction. Find the speed of each particle.
A particle of mass 100 g is kept on the surface of a uniform sphere of mass 10 kg and radius 10 cm. Find the work to be done against the gravitational force between them to take the particle away from the sphere.
