The weight suspended from a spring oscillates up and down. The acceleration of the weight will be zero at

For a particle in $SHM$,if the amplitude of the displacement is $a$ and the amplitude of velocity is $v$,the amplitude of acceleration is

$A$ particle of mass $10 \,g$ is undergoing $S.H.M.$ with an amplitude of $10 \,cm$ and a period of $0.1 \,s$. The maximum value of the force on the particle is about ............ $N$.

Give the direction of velocity and acceleration of an $SHM$ particle.

For a particle performing Simple Harmonic Motion $(S.H.M.)$,the displacement-time graph is as shown. For that particle,the force-time graph is correctly represented by which of the following graphs?

Obtain the formula for the acceleration of a particle from the formula of displacement of $SHM$.
