Please add description.A thin rod of mass `m` and length `2l` is placed horizontally and perpendicular to a horizontal rough nail, as shown in figure and set free. The point of contanct of the rod with the nails is `l//3` distance away form the centre of rod. If the rod starts slipping when it forms an angle `theta` with the horizontal and the coefficient of friction of rod with nails is `mu`, then find `(mu)/(tan theta)`.
