Answer:
0 μC
Explanation:
We need to convert each term to the same units.
1 mC = 1000 μC
1 μC = 1000 nC
First, convert the first term from mC to μC:
+3×10⁻³ mC × (1000 μC / 1 mC) = +3 μC
Next, convert the third term from nC to :
+3×10³ nC × (1 μC / 1000 nC) = +3 μC
Therefore:
(+3×10⁻³ mC) + (-6 μC) + (+3×10³ nC)
(+3 μC) + (-6 μC) + (+3 μC)
0 μC
The sum is 0 μC (or simply 0 C).
