EQUILIBRIA OF PULLEYS

As shown in the following fig.in the given three arrangements A,B and C where pulleys are ideal,strings are light and inextensible,balls attached at the ends of strings are identical and surfaces where the balls rest are frictionless .Identify the nature of equilibria (i.e stable,unstable or neutral) of the arrangements . @Steven Chase @Josh Silverman Now in the figure shown we have to assume that pulley like in A arrangement is also in B and C arrangement but instead of inclined surfaces concavity in B and convexity in C is introduced as it was super hard for me to draw such figures with mouse .PLS give detailed solutions
