Question

consider the free-body diagram. if you want the box to move, the force applied while dragging must be greater than the

Answer 1

Force of static friction between the two surfaces

Step-by-step explanation:

When two surfaces come into contact, they exert a force that resist the sliding of the two surfaces. This force is called static friction.

This force is given by the relation

`F_(s)=\mu_(s)\eta`

Where,

μ - coefficient of static friction

η - normal force acting on the body

When a force acts on a body placed on a rough surface, it doesn't do any work if the applied force was less than the force of static friction.

So, in order to move the body, the applied force should be greater than the force of static friction.
