Question

(40 Points) Class XI
Assertion (A) : When a body completes its round trip', the net work done against
gravitational force is zero.
Reason (R) : Gravitational force is conservative in nature.​

Answer 1

${\boxed{\underline{\tt{ \orange{Required \: \: answer:-}}}}}$

Assertion and Reason are Correct and Reason is the correct Explanation of Assretion.

${\underline{\underbrace{\tt{Understanding \: \: the \: \: concept}}}}$

Gravitational Force is a Conservative Force. A conservative force is one in which the work done is path independent and it only depends upon the position of the object. Hence , The Work Done by Gravitational force is Zero in a Closed Path, Since both the initial and final point are the same.

HOPE IT HELPS.

Answer 2

Answer:

$here \: your \: answer$

Explanation:

◆Assertion and Reason are Correct and Reason is the correct Explanation of Assretion.

Gravitational Force is a Conservative Force. A conservative force exists when the work done by that force on an object is independent of the object's path. Instead, the work done by a conservative force depends only on the end points of the motion. An example of a conservative force is gravity.
