State and explain Kepler’s law for planetary motion.

1.	State and explain Kepler’s law for planetary motion.
Answer» I Law : Every planet moves in an elliptical orbit around the sun with sun at one of the focus. II Law: The line joining the planet to the sun sweeps out equal areas in equal interval of time. III Law: The square of the period of any planet about the sun is proportional to the cube of the semi-major axis of the ellipse.

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
