Let's dive into **Question 2** from your test. Here's a breakdown of each part of the question:

**Question 2:**  
Two blocks with mass 2 kg and \( M \) kg are connected with a light, inelastic string. The string moves over a light, frictionless pulley. The blocks are initially at rest. The static coefficient of friction (\( \mu_s \)) between the 2 kg mass and the surface of the table is 0.3.

1. **2.1:** State Newton's third law in words.  
**Answer:**  
Newton's third law states that *for every action, there is an equal and opposite reaction*. This means that if object A exerts a force on object B, object B exerts a force of the same magnitude but in the opposite direction on object A.

2. **2.2:** Calculate the tension in the string.  
To calculate the tension, we need to consider the forces acting on both blocks. Let’s solve this step by step.

3. **2.3:** Calculate the minimum value of \( M \) that will cause the blocks to move.  
To calculate this, we balance the forces and use the static friction coefficient to find the minimum mass \( M \) required to overcome the friction.

Would you like me to guide you through the detailed calculation process for **2.2** and **2.3**?

This question explores Newton's Third Law and the calculation of tension and friction in a two-block pulley system. It focuses on concepts such as static friction, tension in a string, and the minimum mass needed for movement.
