According to Kepler's second law, the radius vector to a planet from the Sun sweeps out equal areas in equal intervals of time. This law is a consequence of the conservation of ______________.

Text Solution

Verified by Experts

The correct Answer is:
NA
`(dA)/(dt)=L/(2M) =` constant, because angular momentum of planet (`L`) about the centre of the sun is constant. Thus, this law comes from law of conservation of angular momentum.
