Question

Three identical blocks, each of mass m=2 kg, are drawn by a force F=10.2N on a frictionless surface (see figure). What is the tension (in N) in the string between the blocks A and B? (a) 9.2 (b ) 6.8 (c) 4 (d) 9.8​

Answer 1

Answer:

HOPE IT HELPS 1!

Explanation:

Let the tension between B and C be T

M=2kg

F−T=ma

10.2−T=ma

10.2−T=2×0.6

10.2−T=1.2

10.5−1.2=T

T=9N
