State and prove the law of conservation of angular momentum.

Angular momentum is

Angular momentum is

Angular momentum is

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

State the law of conservation of mass.

Define the law of conservation of charge.

The conservation of angular momentum demands that

STATEMENT -1 : Kepler's second law is the consequence of law of conservation of angular momentum. STATEMENT -2 : In planetary motion, the momentum, angular momentum and mechanical energy is conserved. STATEMENT -3 : The gravitational field of a circular ring is maximum at a point upon axis at distance (R )/(sqrt(2)) from the centre, where R is the radius of ring.

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 .
