Question

Identify the incorrect statement about a planet revolving around Sun

• A. The gravitational attraction provides the centripetal force for a revolving planet
• B. The total energy of a planet is always negative
• C. The total energy of a planet is always more than potential energy of the system
• D. Kinetic energy of revolving planet is sometimes zero

Answer 1

The correct option is A The gravitational attraction provides the centripetal force for a revolving planet

The total energy of a planet is always negative.

The total energy of a planet is always more than potential energy of the system.

kinetic energy of revolving planet is sometimes zero.

But, the gravitational attraction provides the centripetal force for a revolving planet is incorrect.

Hence, Option $A$ is incorrect statement.
