Three connected railway coaches A, B and C of masses A m , B m and C m , respectively are being pulled by a locomotive with force F over a horizontal track. The coaches may be assumed to move on frictionless wheels with negligible air resistance. The tension in the connector between coaches A and B is

- A. F
- B. /( ) A A B C Fm m m m + +
- C. /( ) B A B C Fm m m m + +
- D. ( )/( ) B C A B C F m m m m m + + +
Answer: D. ( )/( ) B C A B C F m m m m m + + +
