Question

A point charge of 48 µC is located a very small distance from the center of a very large square on the line perpendicular to the square and going through its center. Determine the approximate electric flux through the square due to the point charge. Answer in units of N · m2 /C

Answer 1

Flux will be
`2.711* 10^6Nm^2/C`

Step-by-step explanation:

We have given point charge
`q=48\mu C=48* 10^(-6)C`

As the point charge is located at very small distance from the center of large square

So the large square behaves as like infinite plane

We know that due to infinite plane electric flux is given by

`\Phi =(q)/(2\epsilon _0)`

So flux
`\Phi =(q)/(2\epsilon _0)=(48* 10^(-6))/(2* 8.85* 10^(-12))=2.711* 10^6Nm^2/C`
