A right solid circular cone standing on its base on a horizontal surface is of height $\text{H}$ and base radius $\text{R}$. The cone is made of a material with specific weight $\text{w}$ and elastic modulus $\text{E}$. The vertical deflection at the mid-height of the cone due to self-weight is given by
- $\frac{\text{wH}^{2}}{8E}$
- $\frac{\text{wH}^{2}}{6E}$
- $\frac{\text{wRH}}{8E}$
- $\frac{\text{wRH}}{6E}$
