A closed surface encloses a net charge of 0.00000210 C. What is the net electric flux through the surface?
To calculate the net electric flux through a closed surface, we need to use Gauss's Law. Gauss's Law states that the net electric flux through a closed surface is equal to the charge enclosed divided by the permittivity of free space (ε0).
The formula for net electric flux through a closed surface is:
Φ = Qenclosed / ε0
Where:
Φ is the net electric flux through the closed surface,
Qenclosed is the charge enclosed by the closed surface,
and ε0 is the permittivity of free space, which is approximately 8.854 x 10^-12 C^2/(N*m^2).
In this case, the charge enclosed (Qenclosed) is given as 0.00000210 C.
Plugging in the values, we have:
Φ = 0.00000210 C / (8.854 x 10^-12 C^2/(N*m^2))
To simplify this calculation, we can divide the numerator and denominator by 0.00000210 C:
Φ = 1 / (8.854 x 10^-12 C/(N*m^2))
Calculating this, we find:
Φ ≈ 11,294,100 N*m^2/C
Therefore, the net electric flux through the closed surface is approximately 11,294,100 N*m^2/C.
Gauss' Law applies.
