Charge Distribution with Spherical Symmetry. A charge distribution has spherical symmetry if the density of charge depends only on the distance from a point in space and not on the direction. In other words, if you rotate the system, it doesn’t look different. For instance, if a sphere of radius R is uniformly charged with charge density …Starting with polar coordinates, we can follow this same process to create a new three-dimensional coordinate system, called the cylindrical coordinate system. In this way, cylindrical coordinates provide a natural extension of polar coordinates to three dimensions.

In cylindrical coordinates, you just go “outward” and then “up or down” to get from the origin to an arbitrary point. The velocity of P is found by differentiating this with respect to time: The radial, meridional and azimuthal components of velocity are therefore ˙r, r˙θ and rsinθ˙ϕ respectively. The acceleration is found by differentiation of Equation 3.4.15. It might not be out of place here for a quick hint about differentiation.

Position-dependent base vectors A difficulty with the cylindrical coordinate formulation is that the base vectors in Eqs. (1)-(3) vary with position; that is, eR and eo are functions of O. This important distinction be- tween cylindrical and Cartesian coordinate formulations complicates several aspects of the finite element formulation ...The "magnitude" of a vector, whether in spherical/ cartesian or cylindrical coordinates, is the same. Think of coordinates as different ways of expressing the position of the vector. For example, there are different languages in which the word "five" is said differently, but it is five regardless of whether it is said in English or Spanish, say.These axes allow us to name any location within the plane. In three dimensions, we define coordinate planes by the coordinate axes, just as in two dimensions. There are three axes now, so there are three intersecting pairs of axes. Each pair of axes forms a coordinate plane: the xy-plane, the xz-plane, and the yz-plane (Figure 2.26).Instagram:https://instagram. grubhub websitedeveloping strategycreston herronis shale an igneous rock The variable θ represents the measure of the same angle in both the cylindrical and spherical coordinate systems. Points with coordinates (ρ, π 3, φ) lie on the plane that forms angle θ = π 3 with the positive x -axis.
