Solution

The correct option is C $\to F$ must be non-conservative
Here, the force is tangential to the curve, hence the work done depends on path. Therefore, force $\to F$ must be non- conservative.
Hence, the correct answer is option (c).

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

The correct option is C →F must be non-conservativeHere, the force is tangential to the curve, hence the work done depends on path. Therefore, force →F must be non- conservative. Hence, the correct answer is option (c).
