Assertion : In keplar's law conservation of angular momentum does not take place. Reason : Gravitation force acting between earth and the sun is perpendicular to line joining them.

Assertion: Kepler's second law can be understood by conservation of angular momentum principle. Reason: Kepler's second law is related with areal velocity which can further be proved to be used on coservation of angular momentum as (dA//dt)=(r^(2)omega)//2 .
