determine the numerical components (projections) of the forces F1,F2,F3 acting on the vertices of the cube OABCDEGH side a in the Oxyz axis system as shown below, knowing F1=100N F2=200\sqrt{2}N , F3=200\sqrt{3}N

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
