Question

State and derive Kepler law of period (or harmonic law) for circular orbits
​

Answer 1

Answer:

This law is known as the law of Periods. The square of the time period of the planet is directly proportional to the cube of the semimajor axis of its orbit. That means the time ' T ' is directly proportional to the cube of the semi major axis i.e. 'a'. Let us derive the equation of Kepler's 3rd law.
