A Charged Isolated Conductor An excess positive charge of 6.46 C is transferred to an isolated spherical conductor of radius R = 13.4 cm. What is the volume
charge density within the sphere in C/m^3?

Determine the moment of the force f about an axis extending between a and c. express the result as a cartesian vector. a is at the origin, c is at (4,3,0) and f = (4i + 12j -3k) lb coming out of b (4,3,-2).
