Where does the electrons go when a short circuit occurs

At the level of an individual electron a short-circuit doesn't look much different than a normal current path, it will move because of the electric field.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
