Question

Calculate value of tension T1, surface is smooth​

Answer 1

Answer:

$T_{1}$ = 60 N.

Explanation:

Let the acceleration of the whole system be "a".

Now,   (5+10+15+25)a = F = 110

     => a = 110/55 = 2.

Now, considering all forces acting of 25 kg block;

 $applied force-tension(1)=25(a)$

=> F - $T_{1}$ = 25a

=> $T_{1}$ = F-25a

         = 110 - 50 = 60N

Answer 2

T1 = 60 N

T2 = 30 N

T3 = 10 N

hope you have your answer :)
