I have solved an equation involving Coulomb's law in two ways and have posted the images of the same. I get two types of equations. Please help me to find where i gone wrong?
Both of your posted solutions appear to give the same quadratic.Thanks Mr. Charles Link. In the first solution i get the q12 -6*10-6q1 -16*10-12 = 0
and for second one i get q12 - 6*10-6q1-16*106 = 0.
My question is why i get different powers for the term involving -16.
