SHMHard
Question
The displacement - time graph of particle executing SHM is shown.
Which of the following statements is / are true?
Which of the following statements is / are true?
Options
A.The velocity is maximum at t = T/2
B.The velocity is maximum at t = T
C.The force is zero at t = 3T/4
D.The potential energy equals the oscillation energy at T/2.
Solution
∵ a = - ω2y and at t = T, y maximum so acceleration is maximum at t.
Also y = 0 at t =
, so force is zero at t = 
At t =
, v = 0 ⇒ PE = oscillation energy
Also y = 0 at t =
, so force is zero at t = At t =
, v = 0 ⇒ PE = oscillation energyCreate a free account to view solution
