Question

The amplitude and the periodic time of shm are 5 cm and 6 seconds respectively at a distance of 2.5 m away from the mean position the phase will be

Answer 1

Dear Student,

◆ Answer -

Φ = π/6

● Explaination -

# Given -

A = 5 cm

T = 6 s

x = 2.5 cm

# Solution -

Let Φ be phase of motion of particle.

x = A.sinΦ

2.5 = 5.sinΦ

sinΦ = 2.5/5

sinΦ = 1/2

Taking sin inverse,

Φ = arcsin(1/2)

Φ = π/6

Φ = 30°

Therefore, phase of motion of particle is π/6.

Thanks dear. Hope this helps you...
