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.
What does the strength of electric force depend on?
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.
What is a strong electric force?
A strong electric field applied between the sharp-edged exit of the capillary and an external electrode causes
charge separation
inside the liquid propellant, which is doped with an additive to increase its electric conductivity.
What two factors affect the strength of an electric field?
A charge is a physical property that describes how charged objects interact with one another. The strength of the electric force is determined by two factors:
Size of the charges –greater the charge the greater the force
.
Distance –closer together the charges are
the greater the force.
Does distance affect electric field strength?
Where the field lines are close together,
the electric field is stronger than where they are farther apart
. The magnitude of the electric field around an electric charge, considered as source of the electric field, depends on how the charge is distributed in space.
How do you know if an electric force is 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
.
Which is the strongest force?
The strong nuclear force, also called the strong nuclear interaction
, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.
Why are electric fields important?
Electric fields (e-fields) are an
important tool in understanding how electricity begins and continues to flow
. Electric fields describe the pulling or pushing force in a space between charges. … The electric fields of single charges. A negative charge has an inward electric field because it attracts positive charges.
How do you calculate the strength of an electric field?
The SI unit of electric field strength is newtons per coulomb (N/C) or volts per meter (V/m). The force experienced by a very small test charge q placed in a field E in a vacuum is given by
E = F/q
, where F is the force experienced.
Can electric field be negative?
Electric field is not negative
. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
What is the factors affecting electric field?
The intensity of the electric field depends by a number of factors such as the
constructive form of the cell, the cell sizes
, the value and the waveform of the supply voltage, the type of insulators used as dielectric barrier.
What is K in electric field?
The Coulomb constant, the electric force constant, or the
electrostatic constant
(denoted k
e

What are the rules for drawing electric field lines?
- 1) Electric field lines are always drawn from High potential to. …
- 2) Two electric field lines can never intersect each other.
- 3) The net electric field inside a Conductor is Zero.
- 4) Electric field line from a positive charge is drawn radially outwards and from a negative charge radially inwards.
What can apply an attractive or repulsive force?
Electromagnetic forces
can be either attractive or repulsive. They are long-range forces, which act over extremely large distances, and they nearly cancel for macroscopic objects.
