# A simple harmonic motion having an amplitude A and time period T is represented by the equation y = 5 sin p (t + 4)m then the values of (A in m) and (T in  sec) are Option 1) A = 5, T = 2 Option 2) A = 10, T = 1 Option 3) A = 5, T = 1 Option 4) A = 10, T = 2

As we discussed in concept

Phase -

The quantity $\phi = wt+\delta$ is called the phase . It determines the status of the particle in simple harmonic motion.

- wherein

e.g.

$x= A\sin \left ( wt +\delta \right )\rightarrow$ phase

$y=5\: sin p (\pi t + 4)$

$w=\frac{2\pi }{T}$

$T=\frac{2\pi }{w}=\frac{2\pi }{\pi }$

$T=2 sec$

$A=5$

Option 1)

A = 5, T = 2

Option is correct

Option 2)

A = 10, T = 1

Option is incorrect

Option 3)

A = 5, T = 1

Option is incorrect

Option 4)

A = 10, T = 2

Option is incorrect
