The direction associated with angular displacement is given by the?
Correct answer: C. Right-hand rule
- A. Left-hand rule
- B. Head to tail rule
- C. Right-hand rule
- D. None of these options is correct
Explanation
Angular displacement is a vector quantity and its direction is along the axis of rotation, which is determined by the "Right-hand rule,' i.e. curling of the "right-hand" leads to fingers pointing along the direction of the circular motion of the particle, and the thumb points in the direction of angular displacement.

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.
