1.

In the figure shown a uniform rod of length l and mass m is kept at rest in horizontal position on an elevated edge. The value of x is such that the rod will have maximum angular acceleration `alpha`, as soon as it is set free.A. x is equal to `(l)/(2 sqrt(3))`B. `alpha` is equal to `(g sqrt(3))/(2l)`C. `alpha` is equal to `(g sqrt(3))/(l)`D. x is equal to `(l)/( sqrt(3))`
