Question

A cube whose sides are of length = 1.8 m is placed in a uniform electric field of magnitude E = 5.8 ✕ 10^3 N/C so that the field is perpendicular to two opposite faces of the cube. What is the net flux through the cube (in N · m^2/C)?

Answer 1

Zero

Step-by-step explanation:

Electric flux is defined as the number of electric field lines which passes through any area in the direction of area vector.

The formula for the electric flux is given by

`\phi =\overrightarrow{E}.\overrightarrow{dS}`

Here, E is the strength of electric field and dS be the area vector.

It is a scalar quantity.

According to the Gauss's theorem, the electric flux passing through any surface is equal to the
`(1)/(\epsilon _(0))` times the total charge enclosed through the surface.

Here, the charge enclose is zero, so the total flux is also zero.
