[Q] Find the integral that represents the flux of the vector F = <x^2z, x^z, x^2z> through the surface S given by z = Ax + By + C for 0 <= x <= a and 0 <= y <= a, where A, B, C, and a are positive constants.
From what I remember of the Flux.
F dot n, where n is a a vector perpendicular to the...
That is correct, there were 5 possible answers but they all had 90k integral 0to7
My answer was correct. :-)
How my professor proceeded.
Given:
Lambda =5c/m
Aofx =0, Bofx =, q = 6c, xp =3, yp=0, zp=2, y=3x^2,
y=y(x), dy(x)/dx = 6c
Fqy = 5kq integral 0to7...
I'm assuming you are using
using U = kqq/r for the potential electro static equation. It isn't in my text, and I just saw that in another related post.
Not sure how I would calculate that atm. My brain is a bit mush. But that does explain a bit of the sign issue I was having with this. I figured it should be negative, but I was just not seeing where it was coming from.
The r value should look something like
([x-3]^2+[3x^2]^2+[2^2])...
Wow I was tired when I posted that.
Starting from the basic force equation.
F = k Qq / r^2
F = k(6) (the tiny cumulative charge as we go across the integral) /(change in distance) ^2
F= 6(5)k(3x^2(1+36x^2)^(1/2))÷(r^2)
F= 90k(x^2(1+36x^2)^(1/2))÷(r^2)
Charged Particle thread with linear charge force
Homework Statement
A uniformly charged thread with linear charge density 5 C/m lies along the curve y = (3/m) x^2 for 0≤x7m. The y component of the electric force it exerts on a 6 C point charge located at (3m, 0m, 2m) is given by...
@jack per the question I actually have to be given that to use it, or the answer is not correct. The whole if your method does not match it is not correct issue.

fun mass calculations
I know the force on the person, and block is the same but I do not know the mass, or ratio of mass. So the closest I can get to knowing the constant accelerations is a = F/mworker/block depending on which mass is used.
While I know about the center of mass, it isn't...

A worker with a mass of Mw is pulling on a mass-less rope that is attached to a box with a mass of mb on a friction-less surface. The worker pulls with a constant force starting at rest. The Worker is at x = 0, and the box is at xb Find the position at which they meet in...
Thank you Office_Shredder for restating what I already knew, AND answering my issue:
" I full well know what a prime number is, and how I would generate them BUT my professor said here you go, and you have to use it without explaining that equation. Having NEVER seen, nor heard of Euler before...
@Scurty That means absolutely nothing to me. I don't have any clue how f(n) = n^s + n + 41 gives me anything useful.
@lurflurf The problem is I have no clue how, or what f(n) = n^2 + n + 41 is supposed to do anything. That is my issue. Based on your answer i am to monkey with the quadratic...
