Assertion : Aeroplanes always shall prefer to fly at low altitudes. Reason : According to Newton's third law of motion, for every action there is an equal and opposite reaction.
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:
Aeroplane wings propel the external air backward, causing the aeroplane to move forward due to the reaction from the expelled air. At lower altitudes, where air density is higher, the aeroplane obtains sufficient force to move forward. So, correct option is (1)

Assertion : Force on a body A by body B is equal and opposite to the force on the body \(B\) by A. Reason : Forces in nature always occur between pairs of bodies.
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:
The force on a body \(A\) by body \(B\) is indeed equal and opposite to the force on body \(B\) by \(A\), according to Newton's third law of motion. This is because forces in nature always occur between pairs of bodies, and for every action, there is an equal and opposite reaction. So correct option is (1)

If action force acting on a body is gravitational in nature, the reaction force
1 May be a contact force
2 Must be gravitational too
3 May be a gravitational or contact force
4 May be a force of any origin

Assertion : Newton's third law applies to all types of forces. \(e.g\). gravitational, electric or magnetic forces etc. Reason : Newton's third law of motion is applicable only when bodies are in motion.
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:
Newton's third law of motion dictates that it is impossible to have a single force arise from the mutual interaction between two bodies, regardless of whether they are in motion or at rest. Newton's third law applies universally to all types of forces. So, correct option is (3)
