NettetThe use of hollow metal spheres as cores for golf balls is disclosed in U.S. Pat. Nos. 6,004,225 and 6,705,957 and in references therein. Due to the higher angular moment of inertia of golf balls of this construction, the impact of a golf club imparts less side-spin than it does to traditional solid-core balls, resulting in improved performance characteristics, … Nettet21. mai 2015 · If you have a conducting hollow sphere with a uniform charge on its surface, then will the electric field at every point inside the shell be 0.. The reason the electric field is 0 at the center is clear from the symmetry of the sphere, but for a point at a certain distance from the center, shouldn't a net electric field exist? food butler
