The correct Answer is:
To match the items in LIST - I with those in LIST - II, we will analyze each type of friction and its characteristics. ### Step-by-Step Solution: 1. **Static Friction (a)**: - Static friction is the frictional force that prevents two surfaces from sliding past each other. It adjusts itself based on the applied force up to a maximum limit. - **Match**: This characteristic is described by option **g) Self adjusting**. 2. **Limiting Friction (b)**: - Limiting friction is the maximum static friction force that can act between two surfaces before they begin to slide. It is a property of the surfaces in contact. - **Match**: This characteristic is described by option **e) Constant for a given pair of surfaces**. 3. **Kinetic Friction (c)**: - Kinetic friction, also known as dynamic friction, occurs when two surfaces slide against each other. It is generally constant for a given pair of surfaces and does not depend on the area of contact. - **Match**: This characteristic is described by option **f) Independent of area of contact**. 4. **Rolling Friction (d)**: - Rolling friction occurs when an object rolls over a surface. It is typically less than static or kinetic friction and has the least magnitude for a given normal reaction. - **Match**: This characteristic is described by option **h) Has the least magnitude for a given normal reaction**. ### Final Matches: - a) Static friction → g) Self adjusting - b) Limiting friction → e) Constant for a given pair of surfaces - c) Kinetic friction → f) Independent of area of contact - d) Rolling friction → h) Has the least magnitude for a given normal reaction ### Summary of Matches: - **a → g** - **b → e** - **c → f** - **d → h**
