A 100 g block is connected to a horizontal massless spring of force constant `25.6(N)/(m)` As shown in Fig. the block is free to oscillate on a horizontal frictionless surface. The block is displaced 3 cm from the equilibrium position and , at `t=0`, it is released from rest at `x=0` It executes simple harmonic motion with the postive x-direction indecated in Fig. The position time `(x-t)` graph of motion of the block is as shown in Fig. Q. When the block is at position B on the graph its.A. position and velocity both are negativeB. position and velocity both are positive.C. position is negative and velocity is positive.D. position is positive and velocity is negative. |

Answer» Correct Answer - D At position B, x is positive and `(dx)/(dt)` is negative. |
