The normal force(the force pushing up from a flat surface) is equal to the force of gravity (the force pushing down on the object) at 5N so they cancel each other out. The other two forces are going in opposite directions, one positive and one negative. Subtracting 10N-5N would give you the amount of force that is not canceled (5N) in the direction of the biggest force (to the left)

Muscular strength is how much you can lift/push/pull, ect. Muscular endurance is how long you can do something with your muscles. Like if you have to put your are straight out in front of you and hold a 25 pound dumbbell. Your will get tired and give out. the more Muscular endurance you have the longer you can do something with your muscles.
