For a planet to be in a stable circular orbit it must have a velocity which is *1 pointPerpendicular to its orbitTangential to its orbitGreater

A planet revolves in elliptical orbit around the sun. The linear speed of planet will be minimum

Choose the incorrect statement from the following:The speed of satellite in a given circular orbit remains constantFor a planet revolving around the sun in an elliptical orbit, the total energy of the planet remains constantThe linear speed of a planet revolving around the sun remains constantWhen a body falls towards earth, the displacement of earth towards the body is negligible

The shape of a planet's orbit is influenced by gravity. True False

Every planet revolves around the sun in an elliptical orbit :A. The force acting on a planet is inversely proportional to square of distance from sun.B. Force acting on planet is inversely proportional to product of the masses of the planet and the sun.C. The centripetal force acting on the planet is directed away from the sun.D. The square of time period of revolution of planet around sun is directly proportional to cube of semi-major axis of elliptical orbit.Choose the correct answer from the options given below :A and D onlyC and D onlyB and C onlyA and C only
