Angle that a body traverses at the centre of a circle in two turns is:
Correct answer: D. 720 degrees
- A. 180 degrees
- B. 360 degrees
- C. 540 degrees
- D. 720 degrees
Explanation
A full turn around a circle is 360 degrees or 2π radians. For two complete turns, multiply the angle of one turn by 2, resulting in 720 degrees or 4π radians. The correct answer is 720 degrees.Option A (180 degrees) is incorrect because it represents only a half turn. Option B (360 degrees) is incorrect because it represents only one turn. Option C (540 degrees) is incorrect because it represents one and a half turns.

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.
