The angle subtended by an arc of length equal to radius of circle is
Correct answer: A. 1 rad
- A. 1 rad
- B. One degree
- C. 1 Revolution
- D. All of these
Explanation
The correct answer is option A: 1 rad. One radian is defined as the angle subtended by an arc of length equal to the radius of the circle. This is a fundamental concept in circular motion and geometry. The other options are incorrect because they do not accurately represent the angle subtended by an arc of length equal to the radius of the circle.

About Angular Displacement
Angular displacement measures the change in a body’s angular position and is expressed in radians or degrees, with anticlockwise and clockwise directions assigned signs. It connects to arc length, angular velocity and angular acceleration, and must be distinguished from ordinary linear displacement in rotational motion.
