PhysicsEasysingle choice

The amplitude and time period in $S H M$ are $0.8 c m$ and $0.2 \sec$ respectively. If the initial phase is $π / 2$ radian, then the equation representing $S H M$ is -

Options:

Answer:

Solution:

Use general equation of SHM

$y = a \sin (ω t + ϕ)$

$= 0.8 \sin \{\frac{2 π t}{0.2} + \frac{π}{2}\}$

$= 0.8 \sin (10 π t + \frac{π}{2})$

$= 0.8 \cos 10 π t$
