Question

Assuming all surfaces to be equally smooth, friction will change if the object is flipped and then dragged, as shown in the figure.

• A. True
• B. False

Answer 1

The correct option is B

False

Friction depends on the nature of surfaces in contact and the force with which the surfaces are pressed against each other. It doesn't depend on the area of contact. Thus, frictional force will not change even if the given object is dragged along the top surface instead of the bottom.
