Statement 1: Force of friction between t...

Statement 1: Force of friction between two surfaces depends on the area of contact common to the two surfaces.
Statement 2: More than area of contact common to the two surfaces, more is the opposition to the motion.

The correct Answer is:
To solve the question, we need to analyze both statements regarding the force of friction and its dependence on the area of contact between two surfaces. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - Statement 1 claims that the force of friction between two surfaces depends on the area of contact common to the two surfaces. - **Analysis**: This statement is **false**. The force of friction does not depend on the area of contact. Instead, it primarily depends on the nature of the surfaces in contact and the normal force acting between them. 2. **Understanding Statement 2**: - Statement 2 states that more the area of contact common to the two surfaces, more is the opposition to the motion. - **Analysis**: This statement is also **false**. The opposition to motion (friction) does not increase with an increase in the area of contact. The frictional force remains constant as long as the normal force is constant, regardless of the contact area. 3. **Conclusion**: - Both statements are false. The force of friction is determined by the coefficient of friction between the materials and the normal force, not the area of contact. ### Final Answer: Both Statement 1 and Statement 2 are false. ---
