Homework Equations
Conservation of Energy
The Attempt at a Solution
I cannot seem to understand the motion involved, especially because the string is inextensible. That means that while the string is taut, if P moves upwards, for example, Q will have to go downwards and vice versa. I tried to do it by considering conservation of energy on P only. I got the thing the question asked to show but with an extra 2gsin(theeta)sin(Beeta) at the end.
So help me out please?
