Solve this : 33 . Displacement - time equation of particle executing SHM is x = Asin ( ωt + ϕ ) . At t = 0 , position of the particle is x = A 2 and it is moving along negative x - direction . Then the angle ϕ can be ( 1 ) π 6 ( 2 ) 5 π 6 ( 3 ) 2 π 3 ( 4 ) π 3 34 . For a particle executing SHM , what is the ratio of average acceleration ( from extreme position to equilibrium position ) to maximum acceleration ? ( 1 ) 4 π ( 2 ) 2 π ( 3 ) 1 π ( 4 ) 1 2 π Share with your friends Share 0 Pintu B. answered this Dear Student , x=A sinωt+ϕNow at t=0 , x=A2 then ,A2=A sinϕ⇒sinϕ=12=Now as the particle is moving along the negative x direction so ,ϕ=π-π6=5π6 Kindly ask different question in different posts only .
