Answer :
Final answer:
To accurately calculate the moment about the base of a pole, the perpendicular distance from the point of force application to the pivot point is required; without it, the correct moment cannot be determined from the given options.
Explanation:
To determine the moment that the man's force exerts about the base of the pole at O, we need additional information such as the perpendicular distance from the line of force to the pivot point O. The moment of a force is calculated as the product of the force applied and the perpendicular distance from the pivot point to the line of force (Moment = Force x Distance). Without this distance, we cannot calculate the actual moment. Assuming the distance is provided as 1 meter in the problem setup, for example, the moment would be 22 Nm (22 N x 1 m). The options given (22 Nm, 44 Nm, 11 Nm, or 33 Nm) suggest different possible distances or scenarios. Without the specific distance or additional context, we cannot provide the correct option from the choices given.
