Homework Statement Homework Equations E = 1/4(\pi \epsilon_{0}) * \frac{p}{r^2} The Attempt at a Solution E = 2\pir_{0} \epsilon_{0} = pl/\epsilon_{0} = \frac{pr}{2\pi r_{0} \epsilon_{0}} I am going by what I know about Gauss Law and using a similar format for the Electric field equation for a...

Thanks. I solved it after looking at a few examples that people had on this site and eventually figured out how they got to the solution. I wouldn't guess it.

\varphi = \vec{E}L^{2}cos(θ) or \varphi = -\vec{E}L^{2}cos(θ) Where E is the electric field from the \hat{n} vector. θ is either 90° or 180° Is that the equation I am looking for?

I really have no clue. This equation is from the book directly.

I see. Let me apply this to the triangle I drew and understand what you said/typed. I'm going to try find a chart or something that has all angles and their sin, cos, and tan to study and memorize them.

I am having trouble with the 2nd question you are asking me. I remembered there was a way to find two unknown sides given only the hypotenuse and the angles. Could you tell me if I am going in the right direction?

For your first question. So we have a 45-45-90 triangle. Hypotenuse is 1 or r=1 (radius) The equation I would use is: x^2 + y^2 = 1 But both sides of the 45-45-90 triangle are the same "n" length. so I would make this equation: 2n^2 = 1 square root both sides to get: sqroot(2)*(n) = 1 divide by...

Ok thanks I will do that. I just have questions like about the Unit Circle. Its been awhile since I lasted used it and I forgot how to use it. What I mean is that I want to understand how to find the next angle of the unit circle like it starts at 0 and the next angle should be pi/6 if I...

I see. Can you recommend any sites, videos, or readings that I can do to help me fully understand this concept or part in Polar Coordinates? I am taking summer courses now and I want to understand everything since its accelerated and I don't want it coming back to bite me when I have to take a...

At its Ames Research Center, NASA uses its large “20-G” centrifuge to test the effects of very large accelerations (“hypergravity”) on test pilots and astronauts. In this device, an arm 8.84 m long rotates about one end in a horizontal plane, and the astronaut is strapped in at the other end...
