It will be directed away from the positive charge. It will attract any other negative charge and repel any positive charge. Its magnitude is given by E= KQ/R where K = 9x 109 C2m-2N-1 Q is the charge producing field R is the point where electric field is to be calculated
Around a positive charge we have a repulsive field and around negative charge we have an attractive field.
Did you mean "The strength of electric field is positive or negative"? Anyway, there is your answer.. The strength of an electric field E at any point is defined as the electric force F exerted per unit positive electric charge q at that point, or E = F/q.You can say that it is positive.
This question is impossible to answer because the force is dependant on the strength of the electric field. This will depend on how many other charges there are and how far away. The strength of an electric field is proportional to the number of charges and the inverse square of the distance. Strength of field = C x N / D2 where C is some constant, N is the number of charges (-ve will repel +ve will attract for and electron) and D is the distance between the electron and the charges creating the field.
positive charge
We could just as well use a negative test charge to determine an electric field, but then the Electric field vector would point opposite the direction of the force on the test charge.
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)
A negative charge is caused by a excess of electrons and a positive charge by their lack.
Everything. A positive charged particle generates an electric field equivalent to the work done in bringing a unit positive charge from infinity to near that charge.

The electric field is defined as the force per unit positive charge that would be experienced by a stationary point charge at a given location in the field.

The electric field lines are directed away from a positive charge and towards a negative charge so that at any point , the tangent to a field line gives the direction of electric field at that point.
