A particle describes a horizontal circle on the smooth surface of an inverted cone, the height of the plane of the circle above the vertex is 9.8 cm. Find the speed of the particle (g= `9.8 m//s^2`) [See Fig.] (a) given in the answer section]

Explanation

To solve the problem of finding the speed of a particle moving in a horizontal circle on the smooth surface of an inverted cone, we can follow these steps:

### Step 1: Understand the Geometry
The height of the circular path above the vertex of the cone is given as \( h = 9.8 \) cm, which we convert to meters:
\[ h = 9.8 \, \text{cm} = 0.098 \, \text{m} \]
