Three point charges arelocated as shown in thefig ure: Q1= +2nC located at y =+2 m Q2+6nC located at x = -3 m, y = -3 m Q3 = +3nC

located at x = +3 m [10 points] Calculate the electric field created by charge Q1 at the origin and draw it on the figure. [10 points] Calculate the electric field created by charge Q2 at the origin and draw it on the figure [10 points] Calculate the electric field created by charge Q3 at the origin and draw it on the figure [10 points] Calculate the electric force on charge q = -2nC located at the origin.
