Net charge charge inside Gaussian surface: Q in = lL. For a converging lens of focal length f, where would you place the object to obtain an This law is an important tool since it allows the estimation of the electric charge enclosed inside a closed surface. We get that $$E=2\int_0^{\pi/2}\text{d}E\cos\alpha=2\int_0^{\pi/2}\frac{\lambda\cos\alpha\text{ d}s}{4\pi\varepsilon_0r^2}.$$, Now, things get a little disturbing for me. The electric field determines the direction of the field. Small $r$ is a function of $\alpha$, so my expression for $\text{d}s$ is wrong. The electric field due to the infinitesimal bit of wire $\text{d}s$ is $\text{d}E=\frac{\lambda\text{ d}s}{4\pi\varepsilon_0r^2}$, and since the vertical components of elements $\text{d}s$ at opposite sides of $O$ will cancel out, what remains is $\text{d}E\cos\alpha$. numbers not all zero, such that a + b +, A:Given Data : V + 1 What is the maximum stopping potential Vo that can Start your trial now! i) Use energy conservation to find a mathematical, A:Given: Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Electric Field of a Long, Uniformly Charged Wire, Help us identify new roles for community members, Calculate electric potential and electric field of uniformly charged wire, Finding the electric field at a point from half of a uniformly charged rod, Calculation of a net electric field for a charged ring - weird integration.
