Answer to Question #179107 in Physics for Fatima Hannah M. Arab

Question #179107

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.

"\\vec{E}_1=\\frac{(9\\cdot10^9)(-5\\cdot10^{-9})}{0.03^2}\\vec{e}_x\\\\\\vec{E}_1=-50000\\vec{e}_x\\frac{V}{m}"

"\\vec{E}_2=\\frac{(9\\cdot10^9)(3\\cdot10^{-9})}{0.04^2}\\vec{e}_y\\\\\\vec{E}_2=16875\\vec{e}_y\\frac{V}{m}\\\\\n\\\\\\vec{E}=(16875\\vec{e}_y-50000\\vec{e}_x)\\frac{V}{m}"
