Problem
Two 20 g worms climb over a 10 cm high, very thin, wall. One worm is thin and 20 cm long. The other is fat (but still thin compared to its length) and only 10 cm long. What is the ratio of the potential energy of the thin worm as compared to that of the fat worm when each is half way over the top of the wall?
(a) 1:1
(b) 2:1
(c) 2:3
(d) 1:2
