The system shown adjacent is in equilibrium. Find the acceleration of the blocks A, B & C all of equal masses m at the instant when (Assume springs to be ideal) 

(a) The spring between ceiling & A is cut. 

(b) The string (inextensible) between A & B is cut. 

(c) The spring between B & C is cut. 

Also find the tension in the string when the system is at rest and in the above 3cases. Solve 3cases seperately.
