# FIGURE EX24.27 shows a hollow cavity within a neutral conductor. A point charge is inside the cavity. What is the net electric flux through the closed surface that surrounds the conductor?

The net electric flux through the closed surface is

See the step by step solution

## Step 1 : Given information and Theory used

Given figure :

Theory used :

The amount of electric field that travels through a closed surface is referred to as the electric flux. The electric flux through a surface is proportional to the charge inside the surface, according to Gauss's law, which is provided by equation :

(1)

## Step 2 : Calculating the net electric flux through the closed surface

The cavity's positive charge induces a negative charge on the conductor's inner side.

As seen in the diagram below, the induced negative charge produces a positive charge at the conductor's surface.

is the total enclosed charge through the closed surface that surrounds the conductor.

To calculate the electric flux, enter this number into equation (1).
