Question

The centre of gravity of a uniform ball is
(a) at its geometrical centre
(b) at its bottom
(c) at its topmost point
(d) at any point on its surface

Answer

(a) at its geometrical centre

Reason — For a uniform ball (a sphere with uniform density), the center of gravity coincides with its geometrical center. This is because the mass of the ball is evenly distributed throughout its volume, leading to a symmetrical distribution of mass around its center. Thus, the center of gravity of a uniform ball is located at its geometrical center.
