The attraction or repulsion between charged particles is called electric force. The strength of electric force depends on the amount of electric charge on the particles and the distance between them. Larger charges or shorter distances result in greater force.
Does electric force depend on the amount of charge and the distance between charges?
How does electric force depend on the amount of charge and the distance between charges? The electric force between two object is directly proportional to the net charge on each object and inversely proportional to the square of the distance between them.
What does electrostatic force depend on?
The electrostatic force has the same form as the gravitational force between two mass particles except that the electrostatic force depends on the magnitudes of the charges on the particles (+1 for the proton and −1 for the electron) instead of the magnitudes of the particle masses that govern the gravitational force.
Why is attractive force negative?
That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational …
What happens to the force if the distance between the charges is cut in half?
According to Coulomb’s law, 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. If the distance between two charges is reduced by half then the force between the two charges is quadrupled.
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.
What makes an electric force stronger?
The strength of the electric force between any two charged objects depends on the amount of charge that each object contains and on the distance between the two charges. As the amount of charge gets bigger, the force gets bigger, and as the distance between the two charges gets larger, the force gets smaller.
How can electric force be reduced?
Inverse relationships are common in nature. In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.
Is an attractive force negative?
9. When they are connected with a wire, the spheres will evenly divide the total charge. Also, an attractive force is negative, and a repelling force is positive.
Is force of repulsion negative?
In general when the force is attractive, the potential energy is negative and as shown above force will be negative. In case of repulsion, with the same argument, the force will be positive.
