Assertion : The work done during a round trip is always zero.
Reason : No force is required to move a body in its round trip.
Explanation:
Definition of Work:
Work is defined as the product of force and displacement in the direction of the force.
Understanding the Assertion:
The assertion states that the work done during a round trip is always zero. In other words, it implies that the net work done on an object during a complete round trip is zero.
Understanding the Reason:
The reason provided for the assertion states that no force is required to move a body in its round trip. This means that the net force acting on the body is zero.
Analysis of the Assertion and Reason:
To analyze the assertion and reason, let's consider the work done during a round trip.
During the first half of the trip, the body is moving in a certain direction, and work is done on the body by the applied force. Let's assume this work to be positive.
During the second half of the trip, the body moves in the opposite direction, and the applied force is opposite to the displacement. Therefore, the work done by the applied force during this half of the trip is negative.
Net Work Done:
The net work done on the body over the entire round trip is the sum of the work done during the first half and the work done during the second half. Since the work done during the first half is positive and the work done during the second half is negative, their sum is zero.
Conclusion:
Hence, the assertion that the work done during a round trip is always zero is correct. However, the reason provided is incorrect because a force is required to move a body in its round trip. The correct reason should state that the net force acting on the body over the entire round trip is zero, not that no force is required.
Correct Answer:
Therefore, the correct answer is option 'D' - Assertion is false but reason is true.
