Questions
For a particle executing S.H.M. the displacement x is given by x = A cos . Identify the graph which represents the variation of potential energy (P.E.) as a function of time t and displacement x
detailed solution
Correct option is A
Potential energy is minimum (in this case zero) at mean position (x = 0) and maximum at extreme position (x = ± A).At time t = 0, x = A, hence potential should be maximum. Therefore graph I is correct. Further in graph III, potential energy is minimum at x = 0, hence this is also correct.Talk to our academic expert!
