Question

Statement I :A ladders is more likely to slip when a person is near the top than when he is near the bottom.
Statement IIThe friction between the ladder and floor decreases as he climbs up.

• A. If both statement I and statement II are true and statement II is the correct explanation of statement I.
• B. If both statement I and statement II are true but statement II is not the correct explanation of statement I.
• C. If statement I is true but statement II is false.
• D. If both statement I and statement II are false.

Answer 1

Answer: (C)

As the person climbs up, normal reaction and friction between the ladder and the wall both increase. This decreases normal reaction from the floor, decreasing limiting value of friction there. This increases the possibility of the ladder slipping
