Looking for help, thanks!

Problem 1: A charge of 91 = 2e sits at Ts = 2i - 3j, where the units of distance are in nanometers (nm) and 1 e = 1.6 x 10-19 C. A second charge, q2 = -e sits at TF = 1i - 2j, where again, the distance units are in nanometers. 1.1 Sketch the vectors T's, TF, and r in the space provided to the left. Then add to the sketch the vector F12 after you have completed the rest of the problem. 1.2 Find the displacement vector, 7 that points from qi to 92, and find its magnitude, r, and the unit vector, r. 1.3 Given that the vector force between two charges is F12 = Anco 72-7, find the vector force that 91 exerts on 92. (The constant Arco = 9 X 105 N m /) ... This is COULOMB'S Law. Memorize it! 1.4 Find the magnitude, F12 of the force, and the angle 0, relative to the x-axis that the force points
