Which of the following graphs are related to a mass m attached to spring performing SHM? Symbols have their usual meaning.
General equation of displacement vs time for a spring block system is
x=A sin(ω t+ϕ)
Ifϕ=0
x=A sinω t
If ϕ isπ2 then general eqn becomes
x=A sin(ω t+π2)
x=A cosω t
The graph will be similar to option (b)
T=2π√mk Time period doesn't depend on Amplitude A
So option c is correct
Kx=−ma
x=−mka
ω2=mk
If k is constant then equation will be similar to y2=x
So option d is wrong
