Name the scientist who explained the motion of planets on the basis of gravitational force between the sun and planets

Who explain the motion of planets around the sun?

Name the scientist who gave the laws of motion.

Name the force responsible for the motion of a planet around the Sun.

Two planets A and B are revolving in circular orbits around a fixed sun. Time period of the planet B is 2sqrt(2) times that of planet A . Find the ratio of solar constant for planet A to that of B . Neglect gravitational force between the planets.

When a planet is orbiting around the sun in an elliptical orbit, r_(1) and r_(2) denote its closest and farthest distances from the sun. Then the ratio of the magnitudes of maximum and minimum gravitational forces between them is

The distance of Pluto from the sun is 40 times the distance of earth. If the masses of earth and Pluto be equal, what will be ratio of gravitational forces of sun on these planets ?

During motion of a planet from perihelion to aphelion the work done by gravitational force of sun on it is

Completion type Question : The motion of planets around the sun is a ………. Dimensional motion.

A planet is revolving around a star in a circular orbit of radius R with a period T. If the gravitational force between the planet and the star is proportional to R^(-3//2) , then
