Angle of friction between any two surfaces in contact is…… of force of limitting friction F and…..makes with…..

Explanation

To solve the question regarding the angle of friction between two surfaces in contact, we will break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Concept of Angle of Friction**:
- The angle of friction (θ) is defined as the angle between the direction of the limiting friction force (F) and the normal force (N) acting on an object resting on a surface.

2. **Identifying Forces Acting on the Object**:
