Question

Three identical blocks of masses m = 2 kg are drawn by a force F = 10.2 N on a frictionless surface, then what is the tension (in N) in the string between the blocks B and C ?

• A. 9.2
• B. 8
• C. 3.4
• D. 9.8

Answer 1

Answer: (C)

3.4

Answer 2

a = $\frac{10.2}{2 + 2 + 2}$, T = 2 × 1.7 = 3.4 N
