Three blocks are connected as shown in fig. on a horizontal frictionless table if \( \mathrm{m}_{1}=1 \mathrm{~kg} \), \( \mathrm{m}_{2}=8 \mathrm{~kg}, \mathrm{~m}_{3}=27 \mathrm{~kg} \) and \( \mathrm{T}_{3}=36 \mathrm{~N}, \mathrm{~T}_{2} \) will be :-
(1) \( 18 \mathrm{~N} \)
(2) \( 9 \mathrm{~N} \)
(3) \( 3.375 \mathrm{~N} \)
(4) \( 1.75 \mathrm{~N} \)
