The question is regarding this image, I understand the two 50N forces provide a clockwise moment of 40 x 10^-2 x 100 which gives option D, as this moment must be balanced by the moment given by T.

Now my question is, how is the net force on this system equal to 0? It says it is in equilibrium which to me means that the net force = 0 and the net moment about any point = 0 but clearly the two vertical forces cancel out (the 50N ones), and then T is left, we know T is non zero so how is the net force 0?

Thank you
