Robert Millikan discovered the electron's charge using the oil drip experiment.
Eugene Goldstein discovered positive particles with the anode/cathode ray tube.
James Chadwick discovered the neutral particle with the beryllium and paraffin wax experiment.
The two types of electric charges are positive and negative. Positive charges repel each other, as do negative charges, while positive and negative charges attract each other.
No electric charges may be positive or negative - electrons have a negative charge; ions have a positive charge.
The electrons; their negativity cancels out the protons' positivity so the atom is electrically neutral.
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)
Electric charges that are the same (positive-positive or negative-negative) repel each other, while charges that are different (positive-negative) attract each other. This is described by Coulomb's law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The two types of electric charges are positive and negative. Positive charges repel each other, as do negative charges, while positive and negative charges attract each other.
Positive electric fields point away from positive charges and towards negative charges, while negative electric fields point towards positive charges and away from negative charges. In both cases, the direction indicates the direction that a positive test charge would move if placed in that field.
Electric field lines go from positive charges to negative charges.
The two types of electric charge are positive and negative. Positive charges repel each other, as do negative charges, while opposite charges attract each other.
The strength of the electric field between positive and negative charges is determined by the magnitude of the charges and the distance between them. The direction of the electric field is from the positive charge to the negative charge.
No electric charges may be positive or negative - electrons have a negative charge; ions have a positive charge.
Similar charges, whether positive or negative, create an electric field around them. This electric field exerts a force on other charges within the field. Positive charges repel other positive charges due to the direction of the electric field, while negative charges repel other negative charges. However, positive and negative charges are attracted to each other because their electric fields pull them towards each other.
A positive electric charge creates an electric field around it and interacts with other charges. It repels other positive charges and attracts negative charges. Positive charges move towards areas of lower voltage in an electric field.
The fundamental property of matter that may be identified as positive or negative is electric charge. Positive charges are carried by protons, negative charges by electrons.
Fundamental laws of electric charges: opposite charges (positive and negative) attract, similar charges (positive and positive or negative and negative) repel, somtimes charged objects will attract a neutral object.
The charges of the objects determine if the electric force is attractive or repulsive. Opposite charges attract each other (positive and negative), while like charges repel each other (positive and positive, or negative and negative).
