The point at which an applied force produces linear motion but no rotatory motion is
Correct answer: A. Mid-point
- A. Mid-point
- B. Centre of gravity
- C. Optical center
- D. Pole
Explanation
The midpoint of an object experiences linear motion but no rotational motion when a force is applied. This is because the force acts symmetrically on both sides of the midpoint, preventing rotation.

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.
