If a planet was suddenly stopped in its orbit supposed to be circular, show that it would fall onto the sun in a time `sqrt(2)/(8)` times the period of the plant's revolution.

The period of revolution of a planet around the sun in a circular orbit is T. If a similar planet is revolving in a circular orbit of the same radius around the sun with its mass twice as that of planet, its period of revolution would be

A planet moving in a circular orbit around the sun at a distance, 4times theaverage distance of the earth from the sun will complete one revolution in

Suppose Earth’s orbital motion around the Sun is suddenly stopped. What time will the Earth take to fall into the Sun?

If a planet of mass m is revolving around the sun in a circular orbit of radius r with time period, T then mass of the sun is

If a and b are the nearest and farthest distances of a planet from the sun and the planet is revolving in an elliptical orbit, then square of the time period of revolution of that planets is directly proportional to

A satellite is revolving around a planet in an orbit of radius R. Suddenly radius of orbit becomes 1.02 R then what will be the percentage change in its time period of revolution?

A planet of mass m is moving in an elliptical orbit about the sun (mass of sun = M). The maximum and minimum distances of the planet from the sun are r_(1) and r_(2) respectively. The period of revolution of the planet wil be proportional to :
