Question

A uniform solid cone of height 40 cm is shown in figure. The distance of centre of mass of the cone from point B (centre of the base) is :

• A. 20 cm
• B. 10/3 cm
• C. 20/3 cm
• D. 10 cm

Answer 1

Answer: (D)

10 cm

Answer 2

The center of mass of a uniform solid cone is located on its axis of symmetry at a distance of $h/4$ from its base, where $h$ is the height. Given $h = 40 \text{ cm}$, the distance from the base (point B) is $40/4 = 10 \text{ cm}$.
