Then, a liquid of density \(\rho = 1000 \text{ kg/m}^{3}\) rises into the cone until no more liquid can possibly enter.

If the normal reaction force per unit length \(N_\lambda\) between the sphere and the walls of the cone can be expressed in SI units as \(\frac{a\sqrt{b}}{c}\) where \(a\), \(b\) and \(c\) are natural numbers with \(b\) square free and \(a\) and \(c\) coprime, what is the value of \(a+b+c\)?

**Details and Assumptions**:

Assume that the sphere forms a tight seal with the walls of the cone and prevents the liquid from rising further

A small hole is present at the vertex of the cone to allow air to escape

Take \(g = 10 \text{m/s}^2 \).
