In the figure shown, find acceleration of the system and tenslons `T_(1),T_(2) and T_(3) (Take = 10 m//s^(2))`

Text Solution

Verified by Experts

`a = ("Net pulling force")/("Total mass")`
`= ((3 + 4 - 2 - 1)g)/(3 + 4 + 2 + 1) = 4m//s^(2)`
`4kg` `40 - T_(1) = 4a :. T_(1) = 24N`
`3kg` `T_(1) + 30 - T_(2) = 3a :. T_(2) = 42N`
`1kg` `T_(3) - 10 = (1) (a) :. T_(3) = 14N`
