AIIMS 2019 Physics Centripetal Force Assertion Reason Question

If the force $F$ acting on an object is always perpendicular to its velocity $V$, it results in a constant change in direction without altering the speed, leading to uniform circular motion. This is because the centripetal force, which is always directed towards the center of the circular path, maintains the circular trajectory. Other options are incorrect because they either misinterpret the relationship between force and motion or incorrectly state the truth value of the assertion and reason. Understanding this principle is crucial in analyzing forces in circular motion, as it highlights the role of perpendicular forces in maintaining a constant radius.
