We will analyse this problem from the reference frame of elava tor. Total buoyant force on the block is FB=(2 5Vρ2+35 Vρ1)(g+a)FB=(25Vρ 2 +35V ρ1)(g+a)
From the condition of equilibrium FB=T+Vd(g +a)FB=T +Vd(g+a) ⇒T=F B−V d(g+a)=(g+a)V[ 25ρ 2+3 5ρ 1−d]⇒T=FB -Vd(g+a)=(g+a)V[25 ρ2+35ρ1- d] =15×10−3[25×1500+35×1000−800]=6N
