- .The electric potential (voltage) in a particular region of space is given by: V(x,y,z) = { K(x³z? - y5) + C)} Where, in the above function, r= (x2 + y2 + z2)% and Kand C are constants... alculate the components of the electric field, Ex, Ey, E,.
*arrow_forward*Consider a point charge q at :=d outside a grounded conducting sphere of radius R, 1. let the image charge be g' at :=d. Show that the potential at any point outside the grounded sphere is, 2. at r= R, we have u(r,0.6) = 0. Use 0 = 0 and e =r to show that, for d> R>d RR-d -RR+d Solution =-. R 3. show that the electric field outside the sphere is, Are (r + d – 2rd cos 8)/2 d (r² + d² – 2rď cos @)a/2*arrow_forward*For problem 11 of the text, calculate the potential in pixpoV at a point r = 0.398 R from the center of the sphere. (5 sig figs)*arrow_forward* - A certain capacitor has rectangular plates 43 cm by 38 cm, and the gap width is 0.20 mm. What is its capacitance? We see that typical capacitances are very small when measured in farads. A one-farad capacitor is quite extraordinary! Apparently it has a very large area A (all wrapped up in a small package), and a very small gap s. i F
*arrow_forward*. Find the potential function and the electric field intensity for the region between two concentric right circular cylinders, where V = 0 at p = 1 mm and V = 150 volts at p = 20 mm.*arrow_forward*way,one of the two infinite conductive planes grounded parallel to the xz plane is at y=0 and the other at y= π. The surface at x=0 is held at potential V0. Find the potential of the system. (I added the mathematical expressions, which are the continuation of the question, to the photo., thanks)*arrow_forward* - Consider the potential distribution V = 5r² sin 0 sin ø. Find: Py everywhere i. ii. The energy required to move 2 µc from A(x=3, y-4, z=5) to B(x=6, y=8, z=10)
*arrow_forward*I have the charge is d a charge o, riting at orizion- sumcounding Cubic bo z made of a perfect Conductor whose sides have length a. The domain of interest is volume Contained by box. a). Find expression of potential associated with this charge (This may be expression as sum). b). Find expression for surface charge density, one of inner walls of box (Again You can express this as sum). found on*arrow_forward*function. 2. Consider a semi-infinite line charge located on the +z axis, with a charge per unit length given by: Ao A(z) = { db e exp(-2/a) z≥0 x 0 are constants. Using spherical coordinates, find the electrostatic potential everywhere, assuming Þ(r → ∞) = 0. It is sufficient to express you answer in terms of definite integrals over r.*arrow_forward* - Please see the upload image. My answer is the one arrow point to. is that correct?
*arrow_forward*An electron is released from rest at a distance d=100 m from an infinite conductingplane. The electron will begin to move towards the plane due to charge inductionin the plane. How long will it take for the electron to strike the plane? I have some work done. Just not sure how to continue. Its attached below. Thanks*arrow_forward*This one is tougher! A sphere of radius r has charge q. (a) What is the infinitesimal increase in clectric potential energy dU if an infinitesimal amount of charge dq is brought to infinity to the surface of the sphere? (b) An uncharged sphere can acquire a total charge Q by the transfer of charge dq over and over and over. Use your answer to part a to find an cxpression for the potential energy of a uniformly-charged sphere of radius R with total charge Q. Answer: U = 3_1 Q² 5 4tc0 R' (c) Your answer to part b is the amount of energy nceded to assemble a charged sphere. It is often called the self-energy of the sphere. What is the self-energy of a proton, assuming it to be a charged sphere with a diamcter of 1.0 x 10 15 m?*arrow_forward*
