Assertion : For two bodies, the sum of the mutual forces exerted between them is zero from Newton's third law Reason : The sum of work done by the two forces must always cancel.
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:
For two bodies, the sum of the mutual forces exerted between them is zero, following Newton's third law. However, the sum of the work done by these two forces may not always cancel out. While sometimes true, it may not hold in all cases. So correct option is (3).

Assertion : Mountain roads rarely go straight up the slope. Reason : Slope of mountains are large therefore more chances of vehicle to slip from roads.
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:
Mountain roads rarely go straight up the slope because the steep slope of mountains increases the chances of a vehicle slipping off the road. The reason correctly explains why mountain roads are typically constructed in a zigzag or 'switch-back pattern'. So correct option is (1)

Assertion : Mass is not conserved separately, but mass and energy are conserved as a single entity called mass energy. Reason : Mass and energy are inter-convertible in accordance with Einstein's relation, \(E=m c^{2}\).
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:
Mass is not conserved separately, but mass and energy are conserved as a single entity called mass-energy. This is in accordance with Einstein's famous relation, \(E=m c^{2}\), which shows the equivalence between mass and energy. So correct option is (1)

The change in kinetic energy per unit 'space' (distance) is equal to
1 Power
2 Momentum
3 Force
4 Pressure
Explanation:
From work energy theorem \(\Delta K=W\) \(\dfrac{\Delta K}{S}=\dfrac{W}{S}=\text { Force }\)
