Electric field is present whenever there are electric charges nearby. This could be due to a stationary charge creating an electric field that spans throughout space, or a changing magnetic field inducing an electric field, as described by Faraday's law of electromagnetic induction.
What else can I help you with?
What is the direction of the electric field in this case?
In this case, the direction of the electric field is determined by the positive charge, pointing away from it.
In which case does an electric field do positive work on a charged particle?
An electric field does positive work on a charged particle when the direction of the electric field is the same as the direction of the particle's movement.
Is the velocity vector perpendicular to electric field affected by electric field?
No, the velocity vector of a charged particle is not affected by the electric field if it is perpendicular to the field. The electric force acting on the particle is zero in this case because the force is given by the product of charge and the component of electric field parallel to the velocity vector.
What is Electric field intensity due to an infinite uniformly uncharged conducting plate?
The electric field intensity due to an infinite uniformly uncharged conducting plate is zero. This is because the charges within the plate are free to rearrange instantaneously to cancel out any external electric field. Therefore, outside the plate, the electric field is effectively zero.
Does electric field and electric field lines connected?
Yes. An electric field is represented by electric field lines. Electric field lines are a visual representation of the strength and direction of an electric field in a region of space. In the vicinity of any charge, there is an electric field and the strength of the electric field is proportional to the force that a test charge would experience if placed at the point. (That is a matter of definition of electric field.) Mother nature produces electric fields, but humans can not see electric fields. Humans invented the idea of field lines to create a mental picture of the field. The two most common ways are to draw lines in space or to draw a collection of arrows in space. In the case of arrows, they are vector representations of the strength and direction of the electric field at the point in space where each arrow is drawn. Representing an electric field (and this works with other fields also) with lines is a sophisticated and time honored tradition. The density of lines in any region of space is proportional to the strength (magnitude) of the field in that region of space. The direction of the field is along the direction of the line at each position on each of the lines. In such a graphical representation the field direction goes out from positive charge and in towards negative charge and the visualization usually has some indication of the sign of charge or direction of the field to give the information about direction of the vector field represented by the field lines. There is a small caveat. It is not only charge that can produce electric fields. An electric field can be produced by a changing magnetic field. This is technologically important (since electric motors work on this principle) and scientifically fascinating, requiring a somewhat more sophisticated aspect of electromagnetic theory, but ultimately the electric field or electric flux can be visualized with lines (or arrows) in a manner exactly as is done for stationary charges.

What is flux density related to?
In case of electrostatics, flux density = electric field intensity and in case of magnetism, flux density = magnetic field induction
An electric field begins on north poles and end on south poles?
That is not correct. Electric field lines originate from positive charges and terminate on negative charges. In the case of a uniform electric field, the field lines run from the positive plate to the negative plate.
What is Electric field intensity due to an infinite uniformly uncharged conducting plate?
The electric field intensity due to an infinite uniformly uncharged conducting plate is zero. This is because the charges within the plate are free to rearrange instantaneously to cancel out any external electric field. Therefore, outside the plate, the electric field is effectively zero.
Where would a person be able to purchase an electric guitar case?
Electric guitar cases are available for purchase from many different stores. Some examples include Sweet Water, SKB Cases, Guitar Center, and Musician's Friend.

Where could one purchase a basketball case?
One can purchase basketball cases online from retailers such as Amazon. Once on the page, type 'case basketball' into the search field at the top of the page and press enter to bring up the cases.
Why there exists magnetic Field when there is no magnetic charges practically?
A magnetic field is induced by moving electric charges, either by an actual electric current, or the way that electrons (charged particles) spin around the nucleus [in the case of magnetic materials becoming magnetized].
What is the plural form of case?
Cases is the plural for case.
What is the electric field on the surface of the conductor?
The field is zero inside only if any charge is evenly distributed on the surface. That's a mathematical theorem, sorry I don't have the proof handy. But when you measure the electric field inside a charged sphere, the charge you use might be large enough to redistribute the surface charge. In this case the electric field will not be zero. Only if you measure at the centre.
