The centre of gravity of a uniform ball is:

Options

A. at is geometrical centre
B. at its bottom
C. at its topmost point
D. at any point on its surface

Explanation

To determine the center of gravity of a uniform ball, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition**: The center of gravity (CG) is the point where the weight of a body is considered to act. For symmetrical objects, this point is often at the geometric center.

2. **Identify the Type of Object**: In this case, we have a uniform ball. A uniform ball means that the mass is distributed evenly throughout its volume.
