For positive angular displacement, the rotation would be:
Correct answer: B. Anti-clockwise
- A. Clockwise
- B. Anti-clockwise
- C. Parallel
- D. Prependicular
Explanation
For positive angular displacement, the rotation would be counterclockwise. The convention for determining the direction of rotation in angular displacement is typically based on the right-hand rule. If you align your right-hand fingers along the axis of rotation in a way that your thumb points in the positive direction of the axis, then the direction your fingers curl is considered to be the positive direction of rotation.

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.
