- Find the electric field (magnitude and direction) at the point P for the following 3-charge configuration, where Q= +1nC and a=2cm. Show detailed work and a free body diagram.arrow_forwardAnswer the following. Show your complete solution by identifying the givenvariables, unknown , formula , solution, and final answer. 1. A point particle of charge 2.5 nC and mass 3.25x10-3 kg is in a uniform electric field directed tothe right. It is released from rest and moves to the right. After it has traveled 12.0 cm, its speedis 25 m/s. Find the (a) work done on the particle, (b) change in the electric potential energy ofthe particle, and (c) magnitude of the electric field.arrow_forwardConsider two point charges of equal magnitude q but opposite sign, separated by a dis- tance d (this is called an electric dipole). 1. Calculate the electric field set up by these two charges, for points in the xz-plane (the field will look the same in any plane containing the z-axis, because of rota- tional symmetry). Work in Cartesian coordinates, with the z-axis passing through the two charges, and the origin halfway between them; thus let the z-coordinate of the positive charge be d/2 and the z-coordinate of the negative charge -d/2. Show that the field is (x,0, z – d/2) (x,0, z + d/2) E(x,0, 2) = 4T€, ((x² + (z – d/2)²)³/2 (x² + (z + d/2)²)³/2, 2. Calculate the far-field approximation for points on the x-axis, i.e. approximate the field at points with z = 0 and with x> d. 3. Do the same for points on the z-axis, i.e. for x = 0 and z » d. Take care that your approximation is not too crude (a 0 answer won't do). To this purpose, bring the two terms of the solution on common…arrow_forward
- Suppose two point charges q and Q are held at distance d and D above an infinite grounded conducting plane (see the Fig. below) where D > d and q = Q.A. Find the potential in the region above the plane using method of images subject to the following boundary conditions:1. V = 0 when z = 02. V⟶ 0 far from the chargeB. Find the force of attraction between the original and the induced image charges also how much Energy all charges will possess in the presence of conductor?arrow_forwardTwo equal disks of external radius R and internal radius R / 2 are loaded with positive and uniform charge distributions σ. The discs lie in parallel planes separated by a distance R, but with their centers located on the same axis, as shown in figure 2. Take this axis as Z, and as the origin of coordinates or the midpoint between the rings. 3. Determine the work that must be done to bring a point charge q from the infinity to point O.arrow_forwardProblem 3.19The potential at the surface of a sphere (radius R) is given by Vo = k cos 30, where k is a constant. Find the potential inside and outside the sphere, as well as the surface charge density o (0) on the sphere. (Assume there's no charge inside or outside the sphere.)arrow_forward
- Consider an infinitesimal segment located at an angular position θ on the semicircle, measured from the lower right corner of the semicircle at x=a, y=0. (Thus θ=π2 at x=0, y=a and θ=π at x=−a, y=0.) What are the x- and y- components of the electric field at point P (dEx and dEy) produced by just this segment? Express your answers separated by a comma in terms of some, all, or none of the variables Q, a, θ, dθ, and the constants k and π.arrow_forwardEquipotential lines for a region are provided below. The lines are separated by 100Vincrements. Which location has the largest magnitude E-field? Smallest? Sketch the electric fieldat each of the labeled locations. Estimate the magnitude of the field at Location C. An electron isshot from A to E with an electron gun. Use a bar chart to explain whether it gains or loses kineticenergy. [Assume no other forces.] Explain and/or show your work for each part.arrow_forwardProblem 3.10 Two semi-infinite grounded conducting planes meet at right angles. In the region between them, there is a point charge q, situated as shown in Fig. 3.15. Set up the image configuration, and calculate the potential in this region. What charges do you need, and where should they be located? What is the force on q? How much work did it take to bring q in from infinity? Suppose the planes met at some angle other than 90°; would you still be able to solve the problem by the method of images? If not, for what particular angles does the method work?arrow_forward
