A devious classmate swings a sharp pencil at the end of some thread capable of withstanding only 10 N of force. Swinging a 20 g pencil in a horizontal, 50 cm radius circle, at what speed will the thread break and possibly strike down an innocent classmate in the prime of life? Also show the force diagram.
