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?
would*

I don't know because I only know pure math and not physics/chemistry
>>8126464
Well, shit.
The water will arch towards the steel.
probably nothing will happen.
>>8126461
nothing would happen.
The only possibility would be something related to electric charge, which is nullified by the conductive property of the steel bar.

What is static electricity?
>>8126593
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.

>If it's conductive, the charge will not stay localized
What are capacitors, retard.
OP, it will bend towards the steel.
>>8126640
You won't have a field inside the conductor but you can have a charge on the conductor and a field outside of it.
>>8126640
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.
>>8126644
>OP, it will bend towards the steel.
why? Water molecules are dipoles, but in normal conditions they're randomly oriented, nothing would happen
>>8126720
If you introduce a field they orient! Hence the bending effect.
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.
>>8126724
you're right, my bad
how big would your field need to be to notice it with your naked eye?
>>8126745
Not huge, you can try it yourself although it's going to be easier for you to charge a plastic rod or something.
>>8126745
Small actually. You can do this with a balloon or piece of plastic rubbed in dry hair
not bend droplets has surface-tension left is pressure

>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...
