No. When discussing an "electric field", we are actually referring to the electrons contained within an object. A "positive electric field" just means that the charge of the object is positive due to the lower amount of electrons in the object. A positive electric field will still in fact attract a positively charged object because there is still an attraction between protons and electrons.
In short, the answer to your question is no.
In most cases yes. Assuming you are talking about A) magnets, B) electrical currents of C) ions. However, if you are in a higher science (College or AP+) Then the answer is no. If you are under 16 or so, just remember positive attracts negative. You have to go very deep into quantum mechanics before you realize that even though the world and all it's processes seem to follow this rule, it doesn't actually exist If you are old enough, I would recommend looking into it because it is interesting. However, you need a profound base knowledge of chem and physics to even begin to understand so just remember for now, opposites attract.
-- The force on a charged object in an electric field depends on the size and sign of
the charge on it, the strength of the electric field, and the direction of the field.
-- If there's another charged object around, then there's also a pair of forces
directly between the two charged objects. That pair of forces depends on the
size and sign of the charge on the two objects, and the distance between them.
-- The total force on each object is the sum of the two forces ... the force due to
the field, and the force due to the other charged object.
Beta radiation, since it is comprised of electrons, and electrons are attracted to the positive electrode or anode.
No, opposite charges (negative and positive) attract, while like charges (pos. and pos. or neg. and neg.) repel each other.
yes. because negative and positives attract each other and negatives and negatives, and positives and positives repeal each other.
Well, Alpha particles are positively charged, so i would think they would be attracted to a negative field.
an alpha particle
True.
Yes.
It will be pushed away from the source of the electric field.
An object becomes positively charged if it loses electrons. This is because electrons have a negative charge, so the less of them there are in an object, the stronger the positive charge is.
A neutral pith ball is still "charged", it just doesn't display excessively charged behavior. Since it is neutral, having nearly equal positive and negative charge, the proximity of the positively charged pith ball still attracts the negative charge present in the ball, inducing polarization moving the ball closer to the positively charged one. Once they make contact, the conductibility of the pith ball quickly accepts excess charge from the other, creating a like charge repulsion.
That depends entirely on sign of the charge. If the object gains a positive charge, then that means the object as lost electrons, since electrons are negatively charge. If the charge is negative, then the object has gained electrons. It is also possible that the charge was created by a movement in protons, which are positively charged, in which case the object may not have lost or gained electrons.
A positively charged particle is called a proton. A negatively charged particle is called an electron.

-- They can if the gravitational force of attraction is greater than the electrostatic force of repulsion between them. -- They also can if they're connected by a rubber band that has been stretched. -- But if the only force between them is the electrostatic force due to their charges, then they must always repel, because their charges have the same sign.
In practical life , it is not possible to identify the negative and positive charges.The positive and negative charges are identified only experimentally.So, practical example of this is not possible.But I can tell that a negatively charged object and positively charged object attract each other.for A+ lost electrons
Yes.
A positively charged object. Like charges repel.

If an object is negatively charged, it has an excess of electrons. If it is positively charged, there are atoms which are short of electrons so you observe the positive charges of the atomic nuclei which are no longer balanced by the electrons that were normally in place.
The " object " would have a positive charge because protons are positively charged./
