A rope of length 2! and uniform density (here: mass per unit length) p is hanging over a nail in a wall with a piece of length I on both sides. Friction, the thickness of the nail, and the thickness of the rope are negligible. \"When one creates a slight length difference between the two sides, a net force will start to act on the rope, and it will slide off the nail, faster and faster. a) (1 point) When the length on one side is E + $[0
