Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Answer is B.
Most air traffic operates at 5,000-40,000 feet when in transits from one airport to another, dipping below these altitudes to take off and land. If they fly at a low altitude above ground level, the curvature of the earth will eventually shield it from detection.
For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs. Hence both assertion and reason are correct but reason is not the correct explanation of assertion.
