The electric force F E F_E FEF, start subscript, E, end subscript can be either attractive or repulsive. Opposite charges, such as a positive charge and a negative charge, attract each other. Like charges, such as two negative charges or two positive charges, will repel each other.
Is electric force attractive or repulsive?
Second, gravitational forces are only attractive; electrical forces can be either attractive or repulsive. The inverse square relationship between force and distance that is woven into the equation is common to both non-contact forces.
Which force is attractive and repulsive?
Note:It is to be noted that the gravitational force is always attractive in nature. Whereas the electrostatic force is either attractive or repulsive. There exists a force of attraction for like charges and force of repulsion for unlike charges.
Why can the electric force be either attractive or repulsive?
The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.
Can positive force be both attractive and repulsive?
The force is repulsive if the particles are both positively or negatively charged; it is attractive if they are of opposite charge.
Is the force between two like masses attractive or repulsive?
Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. The size of the force varies inversely as the square of the distance between the two charges.
What is the electric force attractive?
The electrostatic force is also known as the Coulomb force or Coulomb interaction. It’s the attractive or repulsive force between two electrically charged objects. Like charges repel each other while unlike charges attract each other. Coulomb’s law is used to calculate the strength of the force between two charges.
What causes the attractive and repulsive forces in the atomic model?
(12/14) “It is a matter of attraction. The electrons are attracted to the nuclei because the nuclei are positive and the electrons are negative.” Chemical bond involves both attraction and repulsion forces.
What is repulsive force?
Definitions of repulsive force. the force by which bodies repel one another. synonyms: repulsion. Antonyms: attraction, attractive force. the force by which one object attracts another.
When can you say that an object have a repulsive force between them?
The constant ke is called Coulomb’s constant and is equal to 14πε, where ε is the electric constant; ke = 8.988×109 N⋅m2⋅C−2. If the product q1q2 is positive, the force between the two charges is repulsive; if the product is negative, the force between them is attractive.
Why are repulsive forces positive?
You would have learnt this thing in chemistry (In Atom Structure, you would have calculated energy of electrons for different energy levels b/w electron & proton(nucleus)), that attractive force reduces the energy of the electrons and repulsive force increases the energy of electrons) So since energy corresponding to …
What is the relation between electric force and electric field?
Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.
Which of the following forces are both attractive and repulsive in nature?
Both gravitational and magnetic forces are attractive and repulsive in nature.
Is repulsive or attractive?
Repulsion is a movement between two charges that are identical or similar. The power that exists between two electrons (negative charge). Attraction is a force between two charges that are distinct or unlike.
