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 Simple Harmonic Motion, acceleration a is related to displacement by the relation of the form,
                     a = -kx,
which is for relation (c).
