Consider the following three point charges arranged along the x-axis. (A.) q1 has a charge of -8.0x 10^-6 C and is located at x = -3.0m (b.) q2 carries a charge of 3.0x 10^-6 C and is located at the origin (C.) q3 has a charge of -4.0x 10^-6 C and is located at x = 3.0m. What is the overall force experienced by q2?
