Question

What is the electric charge of a ring-shaped metallic washer ?

Answer 1

Equation of a density of a ring \[\rho(x,y)=(x^2+y^2)^{3/2}\]

Answer 2

Sorry , Real={(x,y)in Real^2 | 1le x^2+y^2 le 2}

Answer 3

x^2+y^2-xy=\frac{x^2}{2}+\frac{y^2}{2}+\frac{(x-y)^2}{2} I Think This What You Have To Do Its Been A While So You Might Want To Double Check

Answer 4

Did You try Working it Out ?

Answer 5

Not sure, but I came up with this

Answer 6

So the charge is π C

Answer 7

i dont have this course till my next year, but whats the formula u are trying to implement?
u want to take the integral of the density at all volume element?

Answer 8

Hey ! Yes since the electric charge can be determined by density and volume it occupies, I decided to implement mass integration but for charge. Something still feels not quite right

Answer 9

Ohh Hold On I Think there is something Missing in that case i was using a different Way to solve it /:

Answer 10

yes thats what i was going to suggest the mass formula for this

Answer 11

but what is that other found on your function?

Answer 12

1<x^2+y^2<?

Answer 13
