.11 T-Mobile Wi-Fi? 9:59 AM courses1.webwork.maa.org (1 point) Two point charges Q1 =4.15 nC and Q-=6.2 nC are shown in the figure. is located at (1.8 cm, 0.0cm) while Q2 is at (0.0 cm.-2.3 cm) (A) Find the components (E and Ey ) for the electric field at (A) which is at the origin. (B) Find the magnitude and angle of the electric field vector E Note: Angles are measured from the positive x axis in the counter-clockwise direction. degrees. Note: You can earn partial credit on this problem. You are in the Reduced Scoring Period: All additional work done counts 80% of the original.

Explanation / Answer

a) Ex = 9x 10^9 (4.15 x 10^-9) / (3.24 x 10^-4) = 11.528 x 10^ 4 N/C

b) Ey = 9x 10^9 ( 6.2 x 10^-9 ) / (5.29x10^-4) = 10.548 x 10^4 N/C

c) E = sqtoot ( Ex^2 + Ey^2)= 15.625 x 10^4 N/C

angle = tan^-1 ( 10.548/11.528)

angle= 222.458 degree apprx
