# Electric Flux

If the total charge on the surface of a conducting sphere is \(2.3 \,\mu\text{C}\) and the diameter of the sphere is \(1.1\text{ m},\) what is the magnitude of the electric field just outside the surface of the sphere, due to the surface charge?

The value of the permittivity constant is \(\varepsilon_0=8.85 \times 10^{-12} \text{ C}^2\text{/N}\cdot\text{m}^2.\)

The value of the permittivity constant is \(\varepsilon_0=8.85 \times 10^{-12} \text{ C}^2\text{/N}\cdot\text{m}^2.\)

Consider a uniformly charged conducting sphere. If the radius of the sphere is \(0.50\text{ m}\) and the surface charge density is \(8.40 \,\mu\text{C/m}^2,\) what is the approximate total electric flux leaving the surface of the sphere?

The value of the permittivity constant is \(\varepsilon_0=8.85 \times 10^{-12} \text{ C}^2\text{/N}\cdot\text{m}^2.\)
