Q.6:- Which of the following relationships between the acceleration a and the displacement x of a particle involve simple harmonic motion?
(a) a = 0.7x
(b) a = –200x2
(c) a = –10x
(d) a = 100x3
Answer:-
In SHM, acceleration a is related to displacement by the relation of the form a = -kx, which is for relation (c).
