Arestoring 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

option A

Explanation:

given,

restoring force = F

magnitude of displacement = x

the system undergo simple harmonic motion.

simple harmonic motion follows Hooke's law

now.

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

hence, the correct answer is option A

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)
