Homework Statement
The masses of blocks A and B in the figure (Figure 1) are 20.0 kg and 10.0 kg, respectively. The blocks are initially at rest on the floor and are connected by a massless string passing over a massless and frictionless pulley. An upward force F⃗ is applied to the pulley.
Find the acceleration b of block B when F is 294 N?

Looking at past problems I got right that were similar.
Essentially, I get it right that the acceleration a of block A is equal to zero at that force and that at 124 N both blocks have acceleration 0, but doesn't that mean that the acceleration of block B is always zero since the it didn't accelerate at 124 N? That was a net force, so it should have caused acceleration yes?
