(a)
The amount of work done by the force along the purple path.
Answer to Problem 45P
The work done by the force along the purple path is
Explanation of Solution
Given info: The coordinates of point (C) is
Along path OA the work is done is only in
Here,
Substitute
The value
Substitute
Thus, work done along OA is
Work done along AC is,
Substitute
The value of
Substitute
Thus, the work done along AC is
The work done along purple path is,
Substitute
Conclusion:
Therefore, the work done in the purple path is
(b)
The amount of work done by the force along the red path.
Answer to Problem 45P
The work done by the force along the red path is
Explanation of Solution
Given info: The coordinates of point (C) is
Work done along OB is,
Substitute
The value of
Substitute
Thus, the work done along the path OB is
Work done along BC is,
Substitute
Along path BC the value of
Substitute
Thus, the work done along the path OB is
The work done along red path is,
Substitute
Conclusion:
Therefore, the work done by the force along the red path is
(c)
The amount of work done by the force along the blue path.
Answer to Problem 45P
The work done by the force along the blue path is
Explanation of Solution
Given info: The coordinates of point (C) is
The work done along the blue path is,
Substitute
The value of
Conclusion:
Therefore, the work done by the force along the blue path is
(d)
Whether
Answer to Problem 45P
The force
Explanation of Solution
Given info: The coordinates of point (C) is
The work done by the force is non conservative in nature as a force is a conservative force if the work done is independent of the path the particle takes.
For the given case the work done in every case is different as the path changes for each of the cases. From the above calculation the work done by the force
Conclusion:
Therefore, the work done by force along every path is different hence it is a non conservative force in nature.
(e)
The reason for the force
Answer to Problem 45P
The work done along each path is different.
Explanation of Solution
Given info: The coordinates of point (C) is
The work done by the force
The work done by the given force
Conclusion:
Therefore, the force is non conservative in nature because work done along each path is different.
