Question

Three identical blocks of masses `m=2kg` are drawn by a force `F=10.2N` with an acceleration of `0.6ms^-2` on a frictionless surface, then what is the tension (in N) in the string between the blocks B and C?

A. (a) 9.2
B. (b) 3.4
C. (c) 4
D. (d) 9.8

Answer 1

Correct Answer - B
`F=(m+m+m)xxa` `:.` `a=10.2/6m//s^2`
`:.` `T_2=ma=2xx10.2/6=3.4N`
