Explanation:
Detailed explanation-1: -The frictional force depends on the shape of the object and the nature of the fluid, hence the given statement is false.
Detailed explanation-2: -Friction is a force that opposes the relative motion between two surfaces in contact. The cause of friction is the interlocking within the irregularities of the two surfaces. As the interlocking is more in rough surfaces, friction is on these type of surfaces. Hence, friction depends on the roughness of the surface.
Detailed explanation-3: -The contact area does not affect friction no matter the surface area.
