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

Text Solution

Verified by Experts

The correct Answer is:
B

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