## What is the electric flux through a surface?

In electromagnetism the term electric flux refers to the measurement of the electric field through a surface. However, an electric field cannot flow by itself. It’s a method of measuring the strength of an electric field at any distance from the source of the field.

### What is the electric flux through the surface shown in Figure ex24 10?

12.5 Nm2/C

**What is the electric flux through a cube? **

According to gauss law the electric flux through closed surfaces is equal to Qe if q is the charge contained in them. If the charge q is placed in one corner of the cube it will be divided into eight such cubes. The eighth part of qe is therefore electric flux through one cube.

**What is the net charge on a conducting sphere of radius 10 Centimetre? **

Because electric field lines are radially inwards the charge on the sphere will be negative. The net charge of the sphere therefore is 6. 67 nC.

## What is the net charge on a conducting sphere of radius?

Therefore, the net charge on a conducting sphere of radius 19 cm is -7.5×10-5C.

### What is the total electric flux leaving the surface of the sphere?

(b What is the total amount of electric flux that leaves the surface the sphere’s surface? The charge on the sphere therefore is 1. 447 x 10-3 C. Therefore, the total electric flux leaving the surface of the sphere is 1. 63 x 108 N C-1 m2.

**Can we have a uniformly charged conducting sphere? **

Gauss’ law can be used to calculate the electric field in a sphere with uniform charge density and a total charge charge Q. Consider a Gaussian surface with radius r> R. The electric field is equal in magnitude at all points and directed outward.

**What is the total electric flux leaving a spherical surface of radius 1 cm and surrounding an electric dipole? **

The total electric flux from the spherical surface’s surface is given by. Flux from the sphere is null.

## What is the angle between the electric dipole moment and?

The direction of the electric field on an equatorial line is reversed to the angle of the axial line. Therefore, the angle between dipole moment and electric field is 180deg.

### What is the magnitude of electric intensity inside a charged hollow sphere?

Now, the charge in the hollow sphere’s hollow is zero. Its flux therefore is also zero. Also, the electric field is also null.

**Why electric field strength in a sphere is zero? **

It is obvious that the electric field directly above a conductor’s surface is directed normal to this surface. The gaussian shell does not contain any charge. All of the charge is on the shell. This follows from Gauss’ law and symmetry.
