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 ______________.

Options

A. linear momentum
B. energy
C. angular momentum
D. all of them

Answer

C

Explanation

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