**m**is moving in an elliptical orbit around the sun of mass

**M**. maximum and minimum distance of the planet from the sun is

**r**and

_{1}**r**. Find the angular momentum of planet about the sun.(Consider M to be fixed in it's position.)

_{2}Angular momentum= m(R*v)

At farthest point from sun angular momentum is mr

_{2}v

_{2}

and at the closest point it is mr

_{1}v

_{1}

I am thinking to make third equation with the forces of interaction between the two bodies bodies. that might be something like centrifugal force = gravitational force of interaction, but i don't know that value of instantaneous radius of curvature of the m at the two points.

So this is my problem. what should i do?
