Distance of the centre of mass of a solid uniform cone from its vertex is `z_0` . If the radius of its base is R and its height is h then `z_0` is equal to:

A

`(h^(2))/(4R)`

B

`(3h)/(4)`

C

`(5h)/(8)`

D

`(3h^(2))/(8R)`

Verified by Experts

The correct Answer is:

B

COM of uniform solid cone of height h
From the base is `(h)/(4)` and
From the vertex is `h-(h)/(4)=(3h)/(4)`
