There are three charges, which are given by Q1 = 1μC, Q2 = 2 μC and Q3 = 3 μC. The field due to each charge at a point P in free space is (ax + 2ay – az), (ay + 3az), and (2ax - ay) Newtons/ Coulomb. The total field at the point P due to all three charges is given by

• A. 1.6ax + 2.2ay + 2.5az Newtons/Coloumb
• B. 0.3ax + 0.2ay + 0.2az Newtons/Coloumb
• C. 3ax + 2ay + 2az Newtons/Coloumb
• D. 0.6ax + 0.2ay + 0.5az Newtons/Coloumb
