Question
A ladder is at rest with its upper end against a wall and the lower end on the ground. Is the ladder more likely to slip, when a man stands on it at the bottom or at the top? Give reason.
✓

Answer

It is more likely to slip when a man stands at the top of the ladder. This is due to the fact that the man's weight will provide an extra torque for the slipping of the ladder.
