Question

Two identical point charges q=71.0 pCq=71.0 pC are separated in vacuum by a distance of 2d=29.0 cm.2d=29.0 cm. Calculate the total electric flux ΦΦ through the infinite surface placed at a distance dd from each charge, perpendicular to the line on which the point charges are located.

Answer 1

The electric flux at the infinite surface is ZERO

Step-by-step explanation:

From the question we are told that

The point charge are identical and the value is
`q = 71.0 pC = 71 * 10^(-12) \ C`

The distance of separation is
`D = 29.0 \ cm = 0.29 \ m`

The distance of both from the infinite surface is d

Generally the electric force exerted by each of the charge on the infinite surface is

`\phi = (q)/(\epsilon_o)`

Now given from the question that they are identical, it then means that the electric flux of the first charge on the infinite surface will be nullified by the electric flux of the second charge hence the electric flux at that infinite surface due to this two identical charges is ZERO
