Final answer:
The angle between the vectors of tangential velocity and centripetal force is 90 degrees because these vectors are perpendicular in uniform circular motion.
The correct answer is C.
Step-by-step explanation:
The student is asking a question related to circle geometry and tangential and centripetal forces in the physics of rotational motion. To determine the angle formed between vectors of tangential velocity and the centripetal force, we utilize the fact that these two vectors are perpendicular to each other in the context of uniform circular motion. Hence, the angle between tangential velocity and centripetal force is 90 degrees.
In the context provided, the angle formed between the vectors of tangential velocity and centripetal force is given as a multiple-choice question. The answer to this question is 90° (c), as these two vectors are always perpendicular to each other in uniform circular motion.
