When a body moves in a circle, the angle between its linear velocity v and angular velocity ω is:

Explanation

In circular motion, the linear velocity v of a body is always tangent to the circle at any point, while the angular velocity ω is directed along the axis of rotation, which is perpendicular to the plane of motion. The angle between the linear velocity vector v and the angular velocity vector ω is always 90 degrees. This is a fundamental relationship in circular motion and holds true at any point along the circular path. Therefore, the correct answer is 90°. Options A, B, and D are incorrect because the angle between the linear velocity and angular velocity vectors is always 90 degrees in circular motion.
