The maximum and minimum distances of the Earth from the Sun respectively are `152xx10^(6)` km and `94.5xx10^(6)` km. the Sun is at one focus of the elliptical orbit. Find the distance from the sun to the other focus.

The maximum and minimum distances of a cornet form Sun are 1.4 xx 10^(12) m and 7 xx 10^(10) m . If velocity nearest to Sun is 6 xx 10^(4) ms^(-1) , what is velocity if cornet when it is farthest from the Sun ?

The maximum and minimum distances of a cornet form Sun are 1.4 xx 10^(12) m and 7 xx 10^(10) m . If velocity nearest to Sun is 6 xx 10^(4) ms^(-1) , what is velocity if cornet when it is farthest from the Sun ?

A planet is revolving round the sun in elliptical orbit. The maximum and minimum distances of the planet from the sun are 2 xx 10^2 m and 2 xx 10^10 m respectively. The speed of the planet when it is nearest to sun is 2 xx 10^15 ms^-1 What is the speed when it is farthest to the sun?
