First coming to the equilibrium part-For the particle under SHM to be in equilibrium it ks obvious that Force acting on the particle must be 0 that means equation for SHM is a=-bx(b=omega squared) so putting a=0(since m cannot be 0 for F to be 0) we have x=0 that means the body is at dynamic quilibrium at its equilibrium (mean)position only.As the body passes through the mean position and start moving towards lets suppose +ve x direction then F acts in opposite direction -ve x so this makes the equilibrium stable.

IN SHM , BY DEFINITION
ACCELARATION SHOULD ALWAYS BE DIRECTED TOWARD CENTRE
CONSIDER A POINT ,
BEFORE AND AFTER ACROSSING THAT POINT ACC. WILL ALWAYS BE DIRECTED TOWARD A PARTICULAR DIRECTION

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
