Q. As per the Kepler’s third law, the square of the time period of revolution of a planet is directly proportional to which of the following?
a. semi-major axis of its elliptical orbit
b. cube root of semi-major axis of its elliptical orbit
c. square of semi-major axis of its elliptical orbit
d. cube of semi-major axis of its elliptical orbit
Kepler’s third law: the square of the time period of revolution of a planet is directly proportional to the cube of semi-major axis of its elliptical orbit. It is also known as the Law of periods.
