Question
A small mass linear S.H.M about O with amplitude ′a′ and period ′T′. Its displacement from O at time T/8 after passing through O is
Options
A.a / 8
B.
C.a / 2
D.
Solution
x = a sin ωt = a sin 
At t =
, x = a sin
= a sin
OR
ω = ωt;φ =
As cos θ =
so x = 
At t =
, x = a sin= a sinOR
ω = ωt;φ =
As cos θ =
so x = Create a free account to view solution
