Given below are two statements: one is labelled as Assertion and the other is labelled as Reason Assertion A: In a central force field, the work done is independent of the path chosen. Reason R: Every force encountered in mechanics does not have an associated potential energy. In the light of the above statements, choose the most appropriate answer from the options given below
Options:
Answer:
B
Solution:
Assertion is correct as central forces are conservative in nature, i.e. work done is independent of path. Reason is true as some forces in mechanics like, friction are non-conservative because work done depends on path and only conservative forces have an associated potential energy. Also, reason does not explain assertion.
