Answer 1
The horizontal component of F decreases


This is correct because as the handle(F) becomes more vertical, the angle increases and the horizontal force(Fh) decreases. (see diagram)

Answer 2
The horizontal component of F increases


This is incorrect because as the angle increases the horizontal force decreases.

Answer 3
The horizontal component of F remains the same.


This is incorrect consult the following diagrams.

What's this question really asking?

This question is really asking, if you had an angle theta and there was a horizontal force involved what would happen to the the horizontal force if theta was increased. return to top
