Professor PC Thomas Classes · Answer

Particles between A and C are moving down after reaching their highest point. Particles between C and $E$ are moving up after crossing the equilibrium position. So the required particle having upward velocity and down ward acceleration is the particle D. Note: Particles above the straight line have downward acceleration. Particles below the straight line have upward accelertion. The straight line represents equilibrium position.\
