Answer #1

NB : - Figure mentioned in the question is not shown

As the box is moving on horizontal floor, and considering the applied force parallel to the floor, the normal force is equal to the weight acting vertically downwards.

Weight = 100 N

∴ Normal force exerted on the block by the floor = 100 N

The second option is the correct answer.

Note: If the applied force is not parallel to the floor, then the answer may change, due to the effect of resolved components of applied force.
