Passage V) In SHM displacement, velocity and acceleration all oscillate simple harmonically with same angular frequency `omega`. Phase difference between any two is `pi/2` except that between displacement and acceleration which is `pi`.
Displacement -time equation of a particle is given as `x=Asin(omegat+pi/6)-A cos(omega+pi/6)`, then:
A. the motion of the particle is not simple harmonic
B. at t=0, acceleration of particles is negative
C. at t-0, velocity of particle is negative
D. None of the above.
