By the superposition property, the resulting field in E is the sum E1+E2 of fields generated by each of charges. Let us calculate each of fields :
- E1=4πε01∣r1−r∣3q1(r−r1)=4π⋅8.85⋅10−1210.082+0.06232⋅10−6⋅(0.08,0.06)
E1=10−39⋅109⋅2⋅10−6⋅10−2⋅(8,6)=(144,108)V/m
- E2=4πε01∣r2−r∣3q2(r−r2)=4π⋅8.85⋅10−1210.082+0.06233⋅10−6⋅(−0.08,0.06)
E2=10−39⋅109⋅3⋅10−6⋅10−2⋅(−8,6)=(−216,162)V/m
Therefore, the total field is E=(−72,270)V/m
