According the Kepler's law, the areal velocity of a planet around the sun, always

According to Kepler's law of planetary motion, if T represents time period and r is orbital radius, then for two planets these are related as

State the Kepler's law which is represented by the relation r^(3) prop T ^(2)

Statement-1: Kepler's law of areas is equivalent to the law of conservation of angular momentum Statement-2: Areal velocity (dA)/(dt)=(L)/(2m)= constant

Kepler's law starts that square of the time period of any planet moving around the sun in an elliptical orbit of semi-major axis (R) is directly proportional to
