Conducting Spheres Problem 4. Identical isolated conducting spheres1 and 2 have equal charges and are seperated by a distance that is large compared with their diameters (a). The electrostatic force acting on sphere 2 due to sphere 1 is F. Suppose now that a third identical sphere 3, having an insulated handle and initia ...continues

A metal sphere of radius a is surrounded by a metal shell of inner radius b and outer radius R, as shown in the diagram below. The flux through a spherical Gaussian surface located between a and b is 0.85Q/εo and the flux through a spherical Gaussian surface just outside R is 1.15Q/εo. What is the total charge ...continues
Physics - new charge distribution
A positive charge Q = 1600.00 C is uniformly distributed over the volume of a sphere of radius R = 5.00 m. Suppose a spherical cavity of radius R/2 is cut out of the solid sphere, the center of the cavity being a distance R/2 from the center of the original solid sphere (image attached). The cut-out material and its charge are d ...continues
