Math Problem Statement
In the following formula, you can figure out relationships between variables, even though you may not know (yet) the meaning of these variables. The electric potential V created at a distance of r from a point source is given by V = C r , and the electric field E is given by E = C r2 , where C is a constant that depends on the source. What would be the relative change in V and in E if the distance r is doubled?
