WebThe problem of determining whether a sphere intersects a cone is equivalent to using Minkowski sums, where the sphere is shrunk to its center point C by its radius rand the cone is expanded to a sphere-swept volume. This volume is formed by placing a spheres of radius rwith centers at the points of the cone, an

How to set up quadratic equation for a ray/sphere intersection?

WebWhen the intersection of a sphere and a plane is not empty or a single point, it is a circle. This can be seen as follows: Let S be a sphere with center O, P a plane which intersects S. Draw OE perpendicular to P and meeting P at E. Let A and B be any two different points in the intersection. WebA hollow sphere, with inner radius a and outer radius b, has a volumetric charge distribution p = kr^2, where r is the distance from the center of the sphere outwards and k is a known constant. Using Gauss's law, find the electric field at r < a, a < r < b, and r > b, and graph the electric field as a function of r.
