Answer:
The flux of the electric field is 677.6 Nm²/C
Step-by-step explanation:
Given that,
Area = 18 cm²
Charge = 6.0 nC
We need to calculate the flux of the electric field
Using Gauss's law

Where, q = charge
=permittivity of free space
Put the value into the formula


Hence, The flux of the electric field is 677.6 Nm²/C.
