Q. The time taken by a particle performing SHM on a straight line to pass from point $A$ to $B$ where its velocities are same in $2$ seconds. After another $2$ seconds it returns to $B$. The time period of oscillation is (in seconds)
Solution:
From the given information it can be inferred that points $A$ and $B$ are equidistant from mean position
Hence it is clear that time period of oscillation is $=2+2+2+2=8$ second
