The system is in equilibrium and the pulleys are frictionless and massless. 5 kg 8 kg 9 kg T Find the force T. The acceleration of gravity is 9.8 m/s 2 . Answer in units of N.

Explanation:

It is given that mass at the right side of the pulley weighs 9 kg, mass at the center weighs 8 kg and mass at the left side weighs 5 kg.

Hence, starting from the right side

              = 9 kg

Now,  

                      = 18 g

Hence, the force balance on 8 kg mass is as follows.

      =

                 = 26 g

Now, force balance on 5 kg mass is as follows.

              5 g + T =

                 T = 47 g

                   =

                   = 460.6 N

Therefore, we can conclude that value of force T is 460.6 N.

the correct choice is a .
