Question

(a) Gradually increase the angle of the incline, but keep the angle low enough that the block does not slide. Select all the phrases below that would make the following statement true: For this situation, as the angle is increased.

a. the maximum possible value of the force of static friction stays the same

b. the force of static friction increases

c. the maximum possible value of the force of static friction increases

d. the force of static friction decreases

e. the force of static friction stays the same

f. the maximum possible value of the force of static friction decreases.

Explanation / Answer

The maximum possible value of static friction remains same and value of static friction gradually increase as static friction is self adjusting force as we increase inclination applied force increase and so static friction wil also increase

Mgsintheta component wil increase on increasing inclination so answer is a and b
