The system shown in the diagram is released from rest. Treat string segments as long. Neglect friction everywhere. Pulley and string are massless. If the time in sec after which block B reaches ground is t. Fill the value of $10 t^{2}$ .

String will slack ( T = 0 ), hence acceleration of B is g ( 10 m / s 2 ) u = 0 , s = 2 m , a = 10 m / s 2 ​ 2 = 2 1 ​ × 10 × t 2 ​ t = 5 2 ​ ​ ​
