Hey, I recently did some tests for a government agency, among those tests were an intelligence test and in that test I got the question:
>"If you have a constant flow of water from a tap and you were to place an electrically charged bit of steel right next to waterflow, what would happen?"
I had some alternatives which I don't really remember, but some of them were: >The water will arch out toward the steel >The water will turn a different colour in the vicinity of the steel
I have no slightest idea what would happen, but out of cheer curiosity, what whould happen?
I don't know because I only know pure math and not physics/chemistry
Christopher Gutierrez
Well, shit.
Colton Davis
The water will arch towards the steel.
Brayden Scott
probably nothing will happen.
Dominic Gutierrez
nothing would happen. The only possibility would be something related to electric charge, which is nullified by the conductive property of the steel bar.
when was the last time you saw a solid piece of metal with a static charge? If it's conductive, the charge will not stay localized. The phrasing in the OP "electrically charged bit of steel" sounds more like it is hooked up to a battery so that the water and the metal so that if the steel WERE touching the water, current would flow from the water to the metal or vice versa.
Noah Bell
>If it's conductive, the charge will not stay localized What are capacitors, retard.
OP, it will bend towards the steel.
Henry Kelly
You won't have a field inside the conductor but you can have a charge on the conductor and a field outside of it.
Christopher Lewis
I didn't see the rod part, assumed that a balloon was used. The static electricity thing bending water is like elementary school science stuff.
Colton Edwards
>OP, it will bend towards the steel.
why? Water molecules are dipoles, but in normal conditions they're randomly oriented, nothing would happen
Andrew Murphy
If you introduce a field they orient! Hence the bending effect.
Noah Watson
It's stupid they consider this "intelligence." This isn't any sort of deductive problem solving. You either were educated about electromagnetism, or you weren't.
Ayden Perez
you're right, my bad
how big would your field need to be to notice it with your naked eye?
Isaiah Clark
Not huge, you can try it yourself although it's going to be easier for you to charge a plastic rod or something.
Robert Gomez
Small actually. You can do this with a balloon or piece of plastic rubbed in dry hair
Daniel White
not bend droplets has surface-tension left is pressure
Lucas Lewis
>yfw when they are testing his general educational background and not his IQ
doesn't take a genius to figure it out, they give the ASVAB to retards, after all...
