Question

A solid cone has a height of $20\text{cm}$. Find the distance of center of mass of the cone from the center of the base of the cone.

• A. $15\text{cm}$
• B. $5\text{cm}$
• C. $10\text{cm}$
• D. $12.5\text{cm}$

Answer 1

The correct option is B $5\text{cm}$


Given, height of the solid cone $\left(H\right)=20\text{cm}$
We know that the center of mass of the solid cone lies at a height of $\frac{H}{4}$ from the center of base of the cone.
So, distance of the center of mass of the cone from the center of base of the cone
$d=\frac{H}{4}=\frac{20}{4}$
$d=5\text{cm}$
