The direction of which angular quantity cannot be measured by the right hand rule?
Correct answer: D. None of the above
- A. Angular velocity
- B. Angular acceleration
- C. Torque
- D. None of the above
Explanation
The right-hand rule is a convention used in physics to determine the direction of a vector quantity based on the orientation of the right hand. It is commonly used to determine the direction of angular velocity, angular acceleration, and torque. Option D is correct, as all of the listed quantities (angular velocity, angular acceleration, and torque) can be measured using the right-hand rule.

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.
