A comet orbits the sun in a highly elliptical orbit. Which of the following quntities remains constant throughout its orbit ?
(i) Linear Spped (ii) Angular speed
(iii) Angular momentum (iv) Kinetic energy
(v) Potential energy (vi) Total energy

A

linear speed

B

angular momentum about the sun

C

kinetic energy

D

potential energy

Text Solution

Verified by Experts

The correct Answer is:
B
In elliptical orbit sun is at one of the foci hence the distance between the planet and sun changes as planet revolves hence linear speed, kinetic energy and potential energy of planet of do not remain constant

A star like the sun has serveral bodies moving around it at different distance. Consider that all of them are moving in circular orbits. Let r be the distance of the body from the centre of the star and let its linear velocity be upsilon , angular velocity omega , kinetic energy K , gravitational potential energy U , total energy E and angular momentum L . As the radius r of the orbit increase, determine which of the above quantities increase and which ones decrease.
