When electric flux is zero then electric field is also zero why?

The electric flux depends on charge, when the charge is zero the flux is zero. The electric field depends also on the charge. Thus when the electric flux is zero , the electric field is also zero for the same reason, zero charge.
Phi= integral E.dA= integral zcDdA = zcQ
Phi is zcQ and depends on charge Q, as does E.

A Gaussian surface does not enclose a charge Does it mean that E equals 0 on its surface?
No.there can be electric field on the Gaussian surface even if the charge enclosed by it is zero.However ,net flux will be zero through the surface.
Where on the axis other than at an infinite distance is there a point at which their net electic field is zero between the charges to their left or to their right explain?
When the two charges are of same polarity then field becomes zero on its axial line but in between the two charges. If they are of opposite polarity then at points outside not in between there will be one point where the net electric field becomes zero. That point will be nearer to the weaker charge ie closer to the weaker and far from the stronger one.
1 A Gaussian surface in the shape of a right circular cylinder with end caps has a radius of 12.0cm and a length of 80.0cm Through one end there is an inward magnetic flux of 25.0µWb At the other e?
Using the Gauss' Law of Magnetism We know total flux will be zero flux(top)+flux(bottom)+flux(curved side)=0 ------- (a) flux(bottom)= -25e-3 (GIVEN) (-ve shows inward direction) flux(top)=B*A=(1.6e-3)*[3.14*(0.12)^2]=2.304e-5 Put the values in eq (a) you'll get flux(curved side)= +24.97e-3 (+ve shows direction is outward)

What is maximum and minimum electric flux?
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
If potential is constant throughout a given region of space can you say that electric field is zero in that region?
If the electric field is zero, the electric potential is a constant value, but it does not tell you what that value is. All the electric field tells you is how the electric potential changes within the region you are looking at. If the electric potential at one end of a cylindrical region is 7 V and the electric field is zero within the whole cylinder, then the electric potential is 7 V at the other end, or somewhere in the middle, or on the side, and so forth. An electric field of zero tells you the potential does not change, but doesn't say anything about what it is outside of the region you're looking at.
What is the electric field half way to the centre of a conducting sphere charged to a potential of 15v?
electric field inside the conducting sphere is ZER0..! because their are equivalent charges all around the sphere which makes the net force zero hence we can say that the electric field is also zero.!
Why induced emf alternates?
Here is A Simple answer for this question as you know that emf is induced in the conductor when there is change of flux linkage to the conductor which gives rise to the inducement of electric field in the conductor that provide drift velocity to the electrons hence emf is induced in the conductor but the last only till the change in flux in progress and becomes zero as soon as the flux linkages becomes constant hence we summaraize that for inducement of current there must be change in change of flux hence change in electric field that gives rise to allternating emf.
What does magnetic flux mean in physics?
The magnetic flux is the measure of the strength of a magnetic field. The total magnetic flux through a closed surface is zero, according to Gauss's law for magnetism.
The electric field inside a hollow uniformly charged sphere is zero Does this imply that the potential is zero inside the sphere Explain?
If the net charge enclosed by a surface is zero then the field at all points on the surface is not zero because gauss's law states that if the charge enclosed by a surface is zero then the flux through the surface is zero which depends upon the magnitude of field and the angle that it makes with the area vector at each point and so it is not necessary that the field will be zero at all points of the surface.
A Gaussian surface does not enclose a charge Does it mean that E equals 0 on its surface?
No.there can be electric field on the Gaussian surface even if the charge enclosed by it is zero.However ,net flux will be zero through the surface.
What is flux residue?
When large magnetomotive force is applied to the core and then removed. The flux in the core doesn't reach zero. Instead, a magnetic field is left behind in the core. This magnetic field is called residual flux in the core. MOHSIN BB-EE-NED
What happens to the strength of the electric field each particle exerts on the other?
The strength of the electric field approaches zero
Moving electric charges will interact with?
Moving electric charges will interact with an electric field. Moving electric charges will also interact with a magnetic field.
How is a charged particle accelerated when the electric field inside the dees of a cyclotron is zero?
it is the magnetic field not the electric field which accelerates the ion inside the dees
What is the phase difference between electric and magnetic field?
Zero.
