A freshly drawn glass fiber (100 µm in diameter) breaks under a tensile load of 40 kN . After subsequent handling, a similar fiber breaks under a tensile load of 0.15 N . Assuming the first fiber was free of defects and that the second fiber broke due to an atomically sharp surface crack, calculate the length of that crack.
