Three identical blocks of masses $m = 2 kg$ are drawn by a force $F = 10.2 N$ with an acceleration of $0.6 ms^{- 2}$ on a frictions surface, then what is the tension (in $N$ ) in the string between the blocks $B$ and $C$ ?

Options:

Answer:

Solution:

Apply Newton's second law $F - T_{ab} = ma; T_{ab} - T_{bc} = ma ∴ T_{bc} = 7.8 N$
