Calculate the magnitude of the electric field at point P. Use the following data: Q1=-1.80 pC, Q2=- 1.40 HC, d1-1.30 m, d2- 1.70 m. 22 P 0 "? 850.1 N/C Submit Answer Incorrect. Tries 1/10 Previous Tries Calculate the size of the force on a charge Q = +1.10 ?C placed at P due to the two charges from the previous problem. 2.035x10-3 N Submit Answer Incorrect. Tries 3/10 Previous Tries

Explanation / Answer

Electric field at P = E = kq1/d1^2 - kq2/d2^2 = 5225.937 N/C

Force on Q placed at P = F = Q*E = 5.7485*10^-3 N
