A drawn glass fiber (100 m diameter) breaks under a tensile load of 40 N. 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.
