List of top Physics Questions on Keplers Laws asked in BITSAT

A satellite is orbiting the Earth and dissipates energy due to some resistive forces. Its initial total mechanical energy is \(E\) (negative). If the radius of its orbit becomes half of the original value, what is the new total mechanical energy of the satellite?
Kepler’s third law states that the square of period of revolution T of a planet around the sun is proportional to the cube of average distance r between sun and planet i.e. T² = Kr³, where K is constant. If the masses of sun and planet are M and m respectively and as per Newton’s law of gravitation the force of attraction between them is F=(GMm)/(r²), where G is gravitational constant, the relation between G and K is described as:
Kepler's third law states that the square of the period of revolution (T) of a planet around the sun is proportional to the third power of average distance r between sun and planet i.e. T² = Kr³, where K is a constant. If the masses of sun and planet are M and m respectively and as per Newton's law of gravitation the force of attraction between them is F=(GMm)/(r²), where G is the gravitational constant. The relation between G and K is described as:
A geo-stationary satellite is one which:
