List of top Physics Questions on Keplers Laws asked in MHT CET

The kinetic energies of planets in an elliptical orbit about the Sun, at positions A, B and C are \(K_{A}\), \(K_{B}\) and \(K_{C}\), respectively. AC is the major axis and SB is perpendicular to AC at the position of the Sun as shown in figure. Then

A planet of mass \(m\) moves in an elliptical orbit around the Sun of mass \(M\). Let \(r_{1}\) be the distance at aphelion and \(r_{2}\) be the distance at perihelion. If \(v_{1}\) and \(v_{2}\) are the velocities of the planet at these points, then ratio of kinetic energy at aphelion to kinetic energy at perihelion is

According to Kepler's second law of planetary motion, the magnitude of areal velocity \(\left(\frac{\Delta A}{\Delta t}\right)\) of a planet of mass '\(m\)' revolving around the sun is constant and is equal to ('\(p\)' is the linear momentum and '\(L\)' is the angular momentum)

A geostationary satellite is orbiting the earth at a height of \(4R\) above the surface of the earth, where \(R\) is the radius of the earth. Another satellite is orbiting the earth at a height \(1.5R\) from the surface of the earth with periodic time 'T' in hour. The value of 'T' in hour is

Two planets A and B are orbiting around the sun. The distances of the two planets A and B from the sun are \(r_A\) and \(r_B\) respectively. Also \(r_B = 225\,r_A\). If the orbital speed of the planet A is 'V' then the orbital speed of planet B will be

What is the ratio of escape velocity to orbital velocity?

The period of revolution of planet A around the sun is 8 times that of \( B \). The distance of \( A \) from the sun is how many times greater than that of \( B \) from the sun?

Two satellites of same mass are launched in circular orbits at heights '$R$' and '$2R$' above the surface of the earth. The ratio of their kinetic energies is ($R = \text{radius of the earth}$)

The time period of a satellite of earth is $5\text{ hours}$. If the separation between the earth and the satellite is increased to four times the previous value, the new time period of the satellite will be

The period of revolution of planet A around the sun is 8 times that of planet B. How many times the distance of A from the sun is greater than that of B from the sun?

If the horizontal velocity given to a satellite is greater than critical velocity but less than the escape velocity at the height, then the satellite will
