Answer both PLEASE and provide full solution and diagram:
1. Point charge q1=-5.00 nC at the origin and point charge q2=+3.00 nC is on the x-axis at x=3.00 cm. Point P is on the y-axis at y=4.00 cm.
a.) Calculate the electric fields E1 and E2 at point P due to the charges q1 and q2. Express your results in terms of unit vectors.
b.) Use the results of part (a) to obtain the resultant field at P, expressed in unit vector form.

2. Point charge q;= -5.00 nC at the origin and point charge q;= +3.00 nC is on the x-axis at x = 3.00 cm. Point P is on the y-axis at y = 4.00 cm a) Calculate the electric fields Ë, at point P due to the charges q: and q: Express your results in terms of unit vectors. b) Use the results of part (a) to obtain the resultant field at P. expressed in unit vector form. '1 and 3. A +2.00 nC point charge is at the origin, and a second-500 nC point charge is on the x-axis at x = 0.800 m. a) Find the electric field (magnitude and direction) at each of the following points on the x-axis: 1) x = 0.200 m; ii) x = 1.20 m; ii) x = -0.200 m. b) Find the net electric force that the two charges would exert on the electron placed at each point in part (a).
