suspended from (a) a rigid rod of negligible mass; and (b) a string
Homework Equations
The Attempt at a Solution
[/B]
I can see that the above solution is not correct.
Do I take the potential energy at A to be 0 and potential energy at ##B=mgy## where y = 4 ?
Can you check this?
Any hints for part (b)?
