Question

In the figure shown, horizontal force F, is applied on a block but the block does not slide. Then as the magnitude of vertical force F, is increased from zero the block begins to slide; the correct statement is 7. 2 ►F (1) The magnitude of normal reaction on block increases (2) Static frictional force acting on the block increases (3) Maximum value of static frictional force decreases (4) All of these ​

Answer 1

Answer:

(3) Maximum value of static frictional force decreases

Explanation:

As the object is lifted a little bit up, the maximum value of static frictional force decreases and hence the figure begins to slide
