A ladder is hanging from ceiling as shownin 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 `2m//s^(2),` C is going up with an acceleration of `1m//s^(2)` and man B is going up with a constantg speed of `0.5` m/s. Find the tension in the string supporting the ledder. `[g=9.8m//s^(2)]`
