Question

three identical blocks of masses m = 2 kg are drawn by a force F = 10.2 N with an acceleration of 0.6 m/s2 on a frictionless surface. What is the tension in the string between blocks B and C

Answer 1

Since, Force = mass × acceleration

F - TAB = ma and TAB - TBC = ma

TBC = F - 2 ma

or TBC = 10.2 - ( 2 x 2 x 0.6)

or TBC = 7.8 N

Answer 2

Answer:

force is mass into acceleration
