Question 937: Electrostats & Capacitance

Question

What is the flux through a cube of side $$a$$ if a point charge of q is at one of its corner?

Accepted Answer

Eight identical cubes are required so that the given charge q appears at the centre of the bigger cube.
Thus, the electric flux passing through the given cube is
$$\phi  = {1 \over 8}\left( {{q \over {{\varepsilon _0}}}} \right) = {q \over {8{\varepsilon _0}}}$$

Answer

$${{2q} \over {{\varepsilon _0}}}$$

Answer

$${q \over {8{\varepsilon _0}}}$$

Answer

$${q \over {{\varepsilon _0}}}$$

Answer

$${q \over {2{\varepsilon _0}}}6{a^2}$$
