How will you find the direction of velocity of a particle moving on a circular path at any instant?

Answer

The direction of velocity at any instant is the direction in which the body tends to move if there is no external force acting on it.
The body in a circular path moves along the tangent drawn to the circle at a point.

Hence, the tangent drawn to the circle at any point gives the direction of the velocity of the body at that point.
