if the angular momentum of planet is constant when its orbiting around the sun then(adsbygoogle = window.adsbygoogle || []).push({});

velocity X radius is a constant

vr=constant

but if we consider the velocity and distance from the sun of the planet in an elipticall orbit to be v and r

the centrepital force is provided by gravitational force then

GMm/r^2 =mv^2/r

GM=v^2r

ie. v^2r=constant

ie. angular momentum is not same in two different position in the elipticall orbit

is what i wrote correct or is there something wrong in the equation
