The relation between acceleration and di...

The relation between acceleration and displacement of four particles are given below. The particle undergoing SHM is:

A

`a_(x) = + 2x`

B

`a_(x) = + 2x^(2)`

C

`a_(x) = -2x^(2)`

D

`a_(x) = 2x`.

Text Solution

Verified by Experts

The correct Answer is:
D

Fo simple harmonic motion, the acceleration must be proportional to negative of displacement i.e. `a prop - y (or x)`
i.e. y (or x) must be linear.
