The difference in lateral pressure, causes a spinning ball to take a curved path which is convex towards the greater pressure side, this effect is called.............

Answer

To solve the question regarding the effect that causes a spinning ball to take a curved path with convexity towards the greater pressure side, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept**: The question describes a phenomenon where a spinning ball curves in its path due to differences in lateral pressure. This is a key concept in fluid dynamics and is related to the behavior of spinning objects in a fluid (like air).

2. **Identifying the Effect**: The effect described is well-known in sports, particularly in games like cricket and soccer, where players spin the ball to control its trajectory. The specific name of this effect is crucial to answer the question.

3. **Recognizing the Name**: The phenomenon where a spinning ball curves due to pressure differences is called the **Magnus Effect**. This effect occurs because one side of the ball experiences higher pressure while the other side experiences lower pressure, causing the ball to curve towards the side with lower pressure.

4. **Conclusion**: Therefore, the answer to the question is that the effect is called the **Magnus Effect**.

### Final Answer:
The effect is called the **Magnus Effect**.
