The amplitude and the time period in SHM are 0.8 cm and 0.2 s respectively. If the initial phase is p/2 radian, then the equation representing SHM is –
A
y = 0.8 cos 10 pt
B
y = 0.8 sin pt
C
y = 3 × 0.8 sin pt
D
y = 0.8 sin 10 pt
Answer
y = 0.8 cos 10 pt
Explanation
Solution
y = a sin (wt + f0)
= 0.8 sin
= 0.8 cos 10pt
