A ladder is hanging from ceiling as shown in figure. Three men A, B and C of masses 40 kg, 60 kg, and 50 kg are climbing the ladder. Man A is going up with retardation 2\[m/{{s}^{2}}\], C is going up with an acceleration of 1 \[m/{{s}^{2}}\]and man B is going up with a constant speed of 0.5\[m/s\]. The tension in the string supporting the ladder is \[240\times x\]Newton then value of x is \[\left[ g=9.8m/{{s}^{2}} \right]\]

Answer:
