Three charges of magnitude 3.0\times 10^{-4}3.0 × 10 − 4 C each are located at x = 1.0 m, y = Three charges of magnitude 3.0\times 10^{-4}3.0 × 10 − 4 C each are located at x = 1.0 m, y = 0.0 m, at x = 0.0 m, y = 0.0 m, and at x = -1.0 m, y = 0.0 m. The one in the middle is negative, while the other two are positive.

What is the net Coulombic force exerted by them on a negative \times10^{-5}3.0 × 10 − 5 C charge located at x = 0.0 m, y = 2.0 m(the value of k is 9.0x10^9 N. m^2/C^2)
