Tardigrade Admin · Accepted Answer

T3=(m1m2+m3)a ⇒ 36=(1+8+27)a ⇒ a=1 m/s2 Now T2 = (m1+m2)a =(1+8)× 1=9 N

Q. Three blocks are connected as shown in figure on a horizontal frictionless table. If $m_{1} = 1 k g, m_{2} = 8 k g, m_{3} = 27 k g$ and $T_{3} = 36 N$ , $T_{2}$ will be

$18 N$

$9 N$

$3.375 N$

$1.75 N$

$T_{3} = (m_{1} m_{2} + m_{3}) a$

$\Rightarrow 36 = (1 + 8 + 27) a$

$\Rightarrow a = 1 m / s^{2}$

Now $T_{2} = (m_{1} + m_{2}) a$

$= (1 + 8) \times 1 = 9 N$
