A body is moving in a circle at constant speed. Which statement is true?
Correct answer: A. The resultant force acts towards the centre of the circle
- A. The resultant force acts towards the centre of the circle
- B. There is no resultant force
- C. The resultant force acts away from the centre of the circle
- D. None of these options are correct
Explanation
The resultant force, being the centripetal force, always acts towards the center of the circle in situations where an object is moving in a circle, at a constant speed.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
