Choose the incorrect statement from the following :
The linear speed of a planet revolving around the sun remains constant.
The speed of satellite in a given circular orbit remains constant.
When a body falls towards earth, the displacement of earth towards the body is negligible.
For a planet revolving around the sun in an elliptical orbit, the total energy of the planet remains constant.
Since planets revolve around the sun in an elliptical orbit its linear speed is not constant, hence option 1 not
correct (and right choice).
Other statement are correct as per theory.
