Physics
For producing the maximum turning effect on a body by a given force, the perpendicular distance of the line of force from the axis of rotation should be :
- minimum
- it does not matter
- maximum
- zero
Answer
maximum
Reason — The torque produced by a force about an axis depends not only on the magnitude of the force but also on the perpendicular distance from the axis of rotation to the line of action of the force. Increasing this distance (having it at a maximum) maximizes the torque produced by the force.
