Two identical beads of \[m=100\] gram are connected by an inextensible massless string can slide along the two arms AC and BC of a rigid smooth wire frame in a vertical plane. If the system is released from rest, the kinetic energy of the first particle when they have moved by a distance of 0.1 m is\[8 \times {{10}^{-3}}J\]. Find the value of \[\operatorname{x}.\left( g=10m/{{s}^{2}} \right)~~~~~~\]
