A uniform ladder of length L and weight w is leaning against a vertical wall. The coefficient of static friction among the ladder and the floor is the same as that among the ladder and the wall. If this coefficient of static friction is µs = 0.510, Decide the smallest angle the ladder can make with the floor without slipping.
