Assertion : The familiar equation \(m g=R\) for a body on a table is true only if the body is in "static-equilibrium". Reason : The equality of \(m g\) and \(R\) has no connection with the third law.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Assertion \(m g=R\) is true for 'static' case shown in figure. In certain scenarios, such as a body in an accelerating lift, the two forces ' \(m g\) ' and ' \(R\) ' can have different magnitudes. The equality of' \(m g\) ' and ' \(R\) ' does not necessarily relate to Newton's third law, as these forces can indeed be unequal. So correct option is (2)

Statement A : The terms action and reaction in the third law of motion stand for simultaneous mutual forces between a pair of bodies. Statement B : In this context action and reaction do not act simulataneously but they act one after the other.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Unlike their meaning in ordinary language, action does not precede or cause reaction. Action and reaction act on different bodies simultaneously. So option (1) is correct.

A father and his seven year old son are facing each other on ice skates. With their hands, they push off against one another. Regarding the forces that act on them as a result of this and the accelerations they experience, which of the following is correct?
1 Father exerts more force on the son and experiences less acceleration.
2 Son exerts less force on the father and experiences more acceleration.
3 Father exerts as much force on the son as the son exerts on the father, but the father experiences less acceleration.
4 Father exerts as much force on the son as the son exerts on the father, but the father experiences more acceleration.

A locomotive (engine) pulls a series of wagons. Which is the correct analysis of the situation?
1 The train moves forward because the locomotive pulls forward slightly harder on the wagons than the wagons pull backward on the locomotive
2 Because action always equals reaction, the locomotive cannot pull the wagons. The wagons pull backward just as hard as the locomotive pulls forward, there is no motion
3 The locomotive’s force on the wagons is as strong as the force of the wagons on the locomotive, but the frictional force on the locomotive is forward and large while the backward frictional force on the wagons is small
