उत्तर
The centre of gravity of a hollow cone of height h is at distance x from its vertex where the value of x is `underline bb((2h)/3)`.
Explanation: The centre of gravity of a hollow cone is at a height of h/3 from the base.
Hence, from the vertex, the height is `"h" - "h"/3`
= `(3"h" - "h")/3`
= `(2"h")/3`
