A particle is subjected to two simple harmonic motion along x and y directions according  $x=3\sin 100\pi t,$$y=4\sin 100\pi t$ 

motion of particle will be on ellipse travelling in clock wise direction 

motion of particle will be on straight line with slope  $\frac{4}{3}$

motion will be simple harmonic motion with amplitude 5

phase difference between two motions is  $\frac{\pi }{2}$
