Current round Cone!

A cone \((\)mass \(m\), radius \(R\), and height \(h)\) has a current \(I\) flowing uniformly along its curved surface area. This cone is kept on a rough surface in a magnetic field \(\vec{B} = B_{0} \hat{i}\).

If the maximum value of current such that the cone doesn't topple about point \(P\) is \(\dfrac{nmg}{\pi B_{0} R},\) determine the value of \(n\).
