The system shown in figure is in equilibrium. Pulley, springs and the strings are massless. The three blocks A, B and C have equal masses. `x_(1)` and `x_(2)` are extensions in the spring 1 and spring 2 respectively. (a) Find the value of `|(d^(2)x^(2))/(dt^(2))|` immediately after spring 1 is cut . (b) Find the value of `|(d^(2)x^(1))/(dt^(2))|` and `|(d^(2)x^(2))/(dt^(2))|` immediately after string AB is cut. (c) Find the value of `|(d^(2)x^(1))/(dt^(2))|` and `|(d^(2)x^(2))/(dt^(2))|` immediately after spring 2 is cut . |

Answer» Correct Answer - (a) `|(d^(2)x_(2))/(dt^(2))| = (3g)/(2)` `|(d^(2)x_(1))/(dt^(2))|= 2g ; |(d^(2)x_(2))/(dt^(2))| = 2g` (c) `|(d^(2)x_(1))/(dt^(2))| = (g)/(2) ; |(d^(2)x_(2))/(dt^(2))| = (3g)/(2)` |
