A particle performs SHM is given by the equation = 20 ( + ), if the time period is 30
and the particle has a displacement of 10 at = 0,
Find (i) epoch,
(ii) the phase angle
at = 5 and
(iii) the phase difference between two positions of the particle 15 seconds
apart.

Explanation:
Correct option is
B
π/10
y=10sin(20t+
3
π
)
Comparing with below equation,
y=Asin(ωt+ϕ) where ω=angular velocity=20
Time period T=
ω
2π
=
ω
2π
=
10
π
