Ans.(3) The object speeds up at P and speeds down at R Because when the object reaches the point P its centripetal force increases due to its centripetal acceleration increases as its radius decreases upto the point Q.
But when the object reaches the point R its centripetal force decreases due to its centripetal acceleration decreases as its radius increases gradually.

An object moves in a circular path at a constant speed. What is the relationship between the directions of the object's velocity and acceleration vectors? The velocity and acceleration vectors point in opposite directions. The velocity and acceleration vectors are perpendicular. The velocity vector points in a direction tangent to the circular path. The acceleration is zero. The velocity vector points toward the center of the circular path. The acceleration is zero. The velocity and acceleration vectors point in the...
