The figure shows the displacement-time graph of a particle executing S.H.M. If the time period of oscillation is 2 sec , the equation of motion of its SHM is :-

Options:

Answer:

Solution:

From the graph: amplitude $A = 10$ , and at $t = 0$ , $x = 5$ .

Let $x = A sin (ω t + ϕ)$ . At $t = 0$ : $5 = 10 sin ϕ \Rightarrow ϕ = π /6$ .

$ω = 2 π / T = 2 π /2 = π$ .

Hence $x = 10 sin (π t + π /6)$ . Answer: option (C).
