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
- A9.2
- B7.8
- C4
- D9.8
Correct answer
B. 7.8
Step-by-step solution
Apply Newton's second law F - T _ ab =m a ; T _ ab - T _ bc = ma T _ bc =7.8 ~N
