A uniform rod of length l and mass m is ...

A uniform rod of length l and mass m is suspended from one end by inextensible string and other end less lies on smooth ground. The angle made by the rod with vertical is `theta="sin"^(-1)(1//sqrt(3))`. If `N_(1)` and `N_(2)` represent the contact force from ground on rod just before and just after cutting the string then the ratio of `N_(1)//N_(2)` is 0.25 x. Find the value of x.
