What is condition for a body suspended at the end of a spring having simple harmonic oscillation ?
Spring must be elastic and oscillation occurs in the absence of resistive force.
A body executes simple harmonic motion under the action of a force $F_1$ with a time period $(4/5)\, sec$. If the force is changed to $F_2$ it executes $SHM$ with time period $(3/5)\, sec$. If both the forces $F_1$ and $F_2$ act simultaneously in the same direction on the body, its time period (in $seconds$ ) is
What is restoring force ?
