1. The problem statement, all variables and given/known data 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 2. Relevant equations a.) what is the force on q2(include direction)? b.) what is the force on q1(include direction)? 3. 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.
