Hello, in the question we have given that a point charge causes an electric field, electric flux of minus 1 into 10 raised to 5 newton meter square per coulomb.
00:12
So, we have given the electric flux.
00:15
So, we have given the electric flux that is equals to so we will write it as phi.
00:24
We will all we will be using phi everywhere.
00:27
So, that is equals to minus 1 into 10 raised to 5 newton meter square per coulomb to pass through a spherical gaussian surface of 10 centimeters radius centered at the charge.
00:43
So, if the radius of the gaussian sphere.
00:46
So, now this is the gaussian sphere they have given and so they are saying that this charge is located over here.
00:55
So, the radius is 10 centimeters.
00:57
Now, if the radius of the gaussian surface here were doubled.
01:03
So, how much flux would pass the surface? so, now in order to answer this we have to see the gauss law.
01:18
Now, according to the gauss law the flux the total electric flux through any closed surface is equal to q enclosed divided by epsilon naught.
01:29
So, now this flux depends from this formula we can see that.
01:34
So, the flux this phi depends phi means flux.
01:42
So, this flux depends on the charge enclosed in the gaussian in the gaussian sphere or the gaussian in the gaussian sphere and not and not on the size of the given body or the object.
02:31
So, now this phi according to the gauss law.
02:35
So, we have this gauss law.
02:36
So, what it states that total electric flux is equal to q enclosed divided by epsilon naught...
