The force by which object tend to pull each other is called

Options

A. attraction
B. repulsion
C. both (a) and (b)
D. neither (a) nor (b)

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept of Force:**
- The question is asking about the force that causes objects to pull each other. In physics, this is a fundamental concept where objects exert forces on one another.

2. **Identifying the Type of Force:**
- The force that causes objects to pull towards each other is known as "attraction." This is the force that makes two objects come closer together.

3. **Defining Attraction:**
- Attraction is the force that acts between two objects that draws them closer together. This can be observed in various scenarios, such as magnets attracting each other or gravity pulling objects towards one another.

4. **Differentiating from Repulsion:**
- It is also important to understand that there is a contrasting force called "repulsion," which occurs when two objects push away from each other. This happens when like poles of magnets are brought together.

5. **Conclusion:**
- Therefore, the force by which objects tend to pull each other is called "attraction."

**Final Answer:**
The force by which objects tend to pull each other is called **attraction**.
