Question

What is the electric flux through one side of a cube that has a single point charge of-2.80μC placed at its center? Hint: You do not need to integrate any equations to get the answer

Answer 1

The flux through one face of a cube is
`- 5.2730* 10^(4) Wb`

Given:

Charge, Q =
`- 2.80\micro C = -2.80* 10^(- 6) C`

Solution:

The electric flux,
`\phi_(E) = (Q)/(\epsilon_(o))`

Since, there are 6 faces in a cube, the flux through one face:

`\phi_(E) = (Q)/(6\epsilon_(o))`

`\phi_(E) = (-2.80* 10^(- 6))/(6\epsilon_(o))`

`\phi_(E) = - 5.2730* 10^(4) Wb`
