If a stone is rotated with the help of a rope, then both centripetal force and centrifugal force will be liberated. The magnitude of that forces are same, but direction of them are opposite to each other.
Again, We know that, centripetal force works toward centre of circle. So why stone does not come back/reach to the centre of circle?
Suppose, for any time $t$ during rotating, stone is situated at point $A$ on the circumference of circle. By drawing a tangent on point $A$ we can show the direction of velocity of stone for that point. Again suppose that after very short interval of time stone reaches at point $B$, and by sketching another tangent on point $B$ we can show the direction of velocity of stone for that point. Will anybody tell me from which two velocity vector this resultant velocity vector for point $B$ will be obtained? If it is possible, please show that with image, or picture.
