Homework Statement
Two point charges are on the x-axis. One charge, q1 = +10nC, is located at the origin, and the other charge, p2=-18nC is located at x = 9.0m
Homework Equations
a.) what is the force on q2(include direction)?
b.) what is the force on q1(include direction)?
The Attempt at a Solution
f=(k(q1q2)/r^2)
f=(9.0*10^9(10*18)/9^2)
K = coulomb's law = 9.0*10^9
I got 1.3122*10^14, but was told that was WAY wrong.
