Question

find the minimum force required to pull a body up a rough inclined surface ?​

Answer 1

Answer:

Therefore, the value of the ratio of the minimum force required to start pushing a body up a rough inclined plane and the minimum force needed to prevent it from sliding down (F1F2) is 3. Hence, the correct answer is 3. Note: For pushing the object both the components of the forces.
