Statement I: A ladder resting against a wall is more likely to slip out at the bottom as a person climbs higher on it.
Statement II: The higher the person climbs, the larger the friction force the ground must supply to keep the ladder in equilibrium.
Options:
Answer:
A
Solution:
Torque balance about the base shows the required friction grows with the height of the person;
once it exceeds limiting friction the foot slips.
Both statements are true.
