If a satellite is revolving around a planet of mass M in an elliptical orbit of semi-major axis a. Show that the orbital speed of the satellite when it is at a distance r from the planet will be given by `v^(2)=GM[2/r-1/a]`

If a satellite is revolving around a planet of mass Min an elliptical orbit of semi-major axis a. Show that the orbital speed of the satellite when it is at a distance are from the planet will be given by v^(2)=GM[2/r-1/a]

If a satellite is revolving around a plenet of mass M in an elliptical orbit of semi-major axis a . Show that the orbital speed of the satellite when it is a distance r from the focus will be given by upsilon^(2) = GM[(2)/(r ) - (1)/(a)]

A planet of mass m is moving around the sun in an elliptical orbit of semi-major axis a :

A satellite revolves around the earth in an elliptical orbit. Its speed is

A planet moves around the sun in an elliptical orbit. When earth is closest from the sun, it is at a distance r having a speed v . When it is at a distance 4r from the sun its speed will be:

A planet is revolving round the sun in an elliptical orbit, If v is the velocity of the planet when its position vector from the sun is r, then areal velocity of the planet is

Speed of a planet in an ellioptical orbit with semimajor axis a about sun of mass M at a distance r from sun is
