A particle moves along a curve of unknown shape but magnitude of force `F` is constant and always acts along tangent to the curve.Then

A

`F` may be conservative

B

`F` must be conservative

C

`F` may be non-conservative

D

`F` must be non-conservative

Text Solution

Verified by Experts

The correct Answer is:
D
In this question, the work done by the force depends upon the path followed by the particle between two positions. Hence the force must be non-conservative.
