The formula for the force \( F \) experienced by a charge \( q \) in an electric field \( E \) is \( F = qE \).
Given:
- \( q = 2 \, \mu C = 2 \times 10^{-6} \, C \)
- \( E = 4 \times 10^3 \, \text{N/C} \)
Substituting these values into the formula:
\[
F = (2 \times 10^{-6}) \times (4 \times 10^3) = 8 \times 10^{-3} \, \text{N}
\]
The resulting force on the charge is \( 8 \times 10^{-3} \, \text{N} \).
