Question

A restoring force of magnitude F acts on a system with a displacement of magnitude x.In which of the following cases will the system undergo simple harmonic motion?

A) F x
B) F
C) F sin x
D) F x2
E) F 1/x

Answer 1

option A

Step-by-step explanation:

given,

restoring force = F

magnitude of displacement = x

the system undergo simple harmonic motion.

simple harmonic motion follows Hooke's law

now.

`F\ \alpha \ x`

Hooke's law state that force is directly proportional to the displacement.

hence, the correct answer is option A
