PHXI03:MOTION IN A STRAIGHT LINE

362283 The displacement \({x}\) of a body in motion is given by \({x=a \sin (\omega t+\theta)}\). The time at which the displacement is maximum is

1 \({\dfrac{\theta}{\omega}}\)
2 \({\left(\dfrac{\pi}{2 \omega}-\dfrac{\theta}{\omega}\right)}\)
3 \({\left(\dfrac{\pi}{2 \omega}\right)}\)
4 \({\left(\dfrac{2 \pi}{\omega}-\dfrac{\theta}{\omega}\right)}\)
