[QUOTE="ehild, post: 4916821, member: 481"] What is h? Recall that the potential energy is as if all the mass of the rod was concentrated in the centre of mass. Correct the expression of the potential energy. And you also miss some parentheses. What is cos(0)? You ignored both cos(0) and the minus sign in front of cos(θ) [/QUOTE]
