Homework Statement
A particle with charge q1 = -6.75x10^-6 is located at (0,3.25x10^-2 m ) and a second particle with charge 3.2x10^-6 is located at (0,-2.75x10^-2 m) what is the electric potential due to the two charges at the origin?
Homework Equations
V = kq/r
The Attempt at a Solution
So at the origin the potential should be kq1/r1 + kq2/r2 = k(q1/r1 + q2/r2)
plugging in, (8.99x10^9)(-1733785 + 1046109) = -6.87x10^5
but my book is telling me the answer is -8.21x10^5
what am I not taking into account here?
