the block shown is on the ground with a vector drawn that shows it's weight: a) how would i complete the vector diagram by drawing another vector that results in zero net force? b) what is the conventional name of the vector drawn?

If the block is not accelerating, then the net force acting on the back must be zero.
Since the force of weight in the diagram is acting straight downward, there must be another force of equal magnitude acting in the opposite direction to counter the weight of the object. This balancing force is known as the "normal force" (F_n) as it acts "normal"/perpendicular to the surface the object rests on.
To complete the force diagram, you'll need to draw aother force pointing straight upward from the block with an equal magnitude of the weight of the black (mg). Doing this will balance the forces and keep the black from accelerating through the ground.

Seriously?
Okay. You draw a vector pointing STRAIGHT UP, with the same magnitude. It's called the normal force vector.
