2. Question 2
   A spider can tell when its web has captured, say, a fly because the fly’s thrashing causes the web threads to oscillate. A spider can even determine the size of the fly by the frequency of the oscillations. Assume that a fly oscillates on the capture thread on which it is caught like a block on a spring.What is the ratio of oscillation frequency for a fly with mass m to a fly with mass 4m?
   • A.1
   • B.2
   • C.4
   • D.8
