late night EE question

[Bluga]

This should be straight Gauss Law, but my answer is not correct:

/***************************************************************************
If measurement have shown that the E-field in all of space is

E = 1/2(Inr) -1/4

find the charge distribution that generated this E-field.
/*************************************************************************

ANS: (epsilon)(lnr)/r

uhhh what year EE are you? I'm a sophomore and I have no clue what you're talking about (but my gpa is like 2.7 so that might have some effect to my knowledge!)

If you're an EE major does that mean you can fix the dead router that I bought? I know it has some kind of power problem...

that looks more like a second semester physics (E&M) question than EE.
took that like in highschool which means i remember nothing. sorry

-patchy

ya, i can probably fix the dead router that you got Just take a multimeter and probe the power supply circuit. Check after the transformer to see if u get some ac voltage, check after the bridge to see if u get a dc voltage. Then look up the spec sheets for some of the ICs that are in there. Probe the power pin and ground to see if you get a voltage... it'll be come obvious where the problem is.

i agree... haven't seen a question like that in a while.... I have no clue...

here's a bump for you, and BTW, V=IR
