Question

A uniformly charged conducting sphere of diameter $3.5 \text{ cm}$ has a surface charge density of $20\mu\text{C m}^{-2}$. The total electric flux leaving the surface of the sphere is nearly}

• A. $57 \times 10^2 \text{ Vm}$
• B. $70 \times 10^2 \text{ Vm}$
• C. $87 \times 10^2 \text{ Vm}$
• D. $35 \times 10^3 \text{ Vm}$

Hint:

Flux depends only on the total enclosed charge, not the distribution. $\Phi = \sigma A / \varepsilon_0$.
