Which of the following relationship between the acceleration, a and the displacement x of a particle involve simple harmonic motion.
(a) `a=7.0x` (b) `a=-200x^(2)` (c) `a=-10x` (d) `a=100x^(3)`

Options

A. `a=0.7x`
B. `a=-200x^(2)`
C. `a=-10x`
D. `a=100x^(3)`

Answer

C

Explanation

In SHM, acceleration a is related to displacement x by the relation of the form `a=-kx`.
