a planet is moving in an elliptical path around the sun.P and Q are two points on a straight line in the elliptical path collinear with the sun.given SP=R1 and SQ=R2.v1 and v2 are velocities of the planet at P and Q respectively.find v1/v2

motion of particle is elleptical & angular momental of particle about sun at every point is conserved..

for point p

              Jp=MV1 R1

for point q

             Jq=MV2R2

for conservation of angular momentam

 MV1R1 = MV2R2

   V1/V2 =R2/R1
