Question

Which one of the following relationships between the acceleration a and the displacement x of a particle
involve simple harmonic motion

(a) a)a=15x
b) a = -5x
c) a = = 200x2
d) a = 100x3​

Answer 1

Answer:

F=−kx

ma=−kx

a=

m

−kx

For SHM, acceleration should be directly proportional to displacement and sign should be negative. Hence, (c) represents SHM.
