Pls ! how we calculate this?
you if you solve

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).
