Homework Statement
Consider two equal positive charges (q=+2.0 µC) a distance of 3.0 cm apart. What is the electric potential midway between the two charges? What is the E field at this point?
I got the work and everything all solved out, i just don't know where some of the numbers came from. Where does the 2 before K come from, I understant the q= 2X10^-6, but why is r 1.5x10^-2? I am just wondering where some of the numbers came from.
