Directions: Each of these questions contain two statements, Assertion and Reason. Each of these questions also has four alternative choices, only one of which is the correct answer. You have to select one of the codes (a), (b), (c) and (d) given below.
Assertion: If a body of mass m is projected upwards with a speed V making an angle ? with the vertical, than the change in the momentum of the body along X–axis is zero.
Reason: Mass of the body remains constant along X–axis
  • a)
    Assertion is correct, reason is correct; reason is a correct explanation for assertion.
  • b)
    Assertion is correct, reason is correct; reason is not a correct explanation for assertion
  • c)
    Assertion is correct, reason is incorrect
  • d)
    Assertion is incorrect, reason is correct.
Correct answer is option 'B'. Can you explain this answer?

Directions: Each of these questions contain two statements, Assertion...
Explanation:
- The assertion states that if a body of mass m is projected upwards with a speed V, making an angle θ with the vertical, then the change in momentum of the body along the X-axis is zero.
- The reason given is that the mass of the body remains constant along the X-axis.

Understanding the Assertion:
- When a body is projected upwards at an angle θ with the vertical, it can be resolved into two components of motion - one along the vertical axis (Y-axis) and the other along the horizontal axis (X-axis).
- The change in momentum of the body along the X-axis is zero because there is no external force acting along the X-axis to change the momentum of the body.
- The only force acting on the body along the X-axis is the force of gravity, which acts vertically downwards and does not cause any change in momentum along the X-axis.

Understanding the Reason:
- The reason given is that the mass of the body remains constant along the X-axis.
- The mass of an object is a scalar quantity and does not change with direction or axis.
- Therefore, the mass of the body remains constant along the X-axis.

Explanation of Correct Answer:
- The correct answer is option 'B' - Assertion is correct, reason is correct; reason is not a correct explanation for assertion.
- The reason given does not explain why the change in momentum along the X-axis is zero.
- The reason only states that the mass of the body remains constant along the X-axis, which is a general property of mass and does not provide an explanation for the assertion.
- The assertion is correct because there is no external force acting along the X-axis to change the momentum of the body.
- However, the reason given is not a correct explanation for the assertion as it does not provide any insight into why the change in momentum along the X-axis is zero.

Conclusion:
- In conclusion, the change in momentum of a body projected upwards at an angle with the vertical along the X-axis is zero because there is no external force acting along the X-axis to change the momentum of the body. The reason given, that the mass of the body remains constant along the X-axis, is not a correct explanation for the assertion.

When a body is projected up making an angle ? the velocity component along-axis remains constant. Therefore, Momentum along x-axis is constant. Along horizontal, mass and velocity both are constant.
