Electrostatic force on the particle

In summary, if a charged particle is located inside a shell of uniform charge, there will be no net electrostatic force on the particle from the shell. This is due to the fact that the electrostatic force is directly proportional to charge and inversely proportional to the square of the distance. For spherical shells, this fact holds true, while for non-spherical shells it is approximately true if the distance from the particle to the shell is large compared to the change in "radius" of the shell.

if a charged particle ic located inside a shell of uniform charge there is no net electrostatic force on the particle from the shell.
1st is this fact?
2nd if it is so please explane it to because there is some distance between the particle and other chargeds in shell every one has different distance from anther?.:smile:

The electrostatic force is directly proportional to charge.
The electrostatic force is directly proportional to [itex]1/r^2[/itex].
But the charge is directly proportional to [itex]r^2[/itex].

Think about this and see for yourself if it is true.

Yes, it is a fact for spherical shells. For non-spherical shells it will be approximately true if the distance from the particle to the shell is large compared to the change in "radius" of the shell.

I have no idea what you mean by "every one has different distance". Isn't that always true?

Draw four straight lines from one side of the shell through the particle to the other side. The area of the shell contained within those four lines on one side offsets the area on the other side because, as Haywire said, the the ratio of the two areas is equal to the ratio of the distances squared, while the ratio of the forces due to the charge in each area is equal to the one over the ratio of the distances squared.
 

What is electrostatic force on a particle?

Electrostatic force on a particle is the force that results from the interaction between electrically charged particles. It is a fundamental force of nature that is responsible for the attraction or repulsion of particles based on their electric charge.

What is the equation for calculating electrostatic force on a particle?

The equation for calculating electrostatic force on a particle is F = (k * q1 * q2) / r2, where F is the force, k is the Coulomb's constant, q1 and q2 are the charges of the two particles, and r is the distance between them.

How does the distance between two charged particles affect the electrostatic force?

The electrostatic force between two charged particles is inversely proportional to the square of the distance between them. This means that as the distance between the particles increases, the force decreases and vice versa.

What factors determine the strength of electrostatic force on a particle?

The strength of electrostatic force on a particle is determined by the magnitude of the charges on the particles and the distance between them. The larger the charges and the smaller the distance, the stronger the force will be.

What is the difference between electrostatic force and gravitational force?

Electrostatic force is the force between charged particles, while gravitational force is the force between objects with mass. Electrostatic force is much stronger than gravitational force, but it only affects charged particles, while gravitational force affects all objects with mass.
