"the net force on system under electrostatic force will always be equa...
Explanation of the statement: "The net force on a system under electrostatic force will always be equal to zero."


What is electrostatic force?

Electrostatic force is the force that exists between electrically charged particles. It can be attractive or repulsive, depending on the charges of the particles.

What is a system?

In physics, a system is a collection of objects that we are interested in studying. These objects can be anything from particles to planets.

What is net force?

Net force is the vector sum of all the forces acting on an object or a system. If the net force on an object is zero, then the object is said to be in equilibrium.

Why is the net force on a system under electrostatic force always equal to zero?

The net force on a system under electrostatic force is always equal to zero because of the following reasons:


  1. Newton's third law: According to Newton's third law, every action has an equal and opposite reaction. This means that if two charged particles exert a force on each other, the force that one particle exerts on the other is equal in magnitude and opposite in direction to the force that the other particle exerts on the first particle. As a result, the net force on the system is always zero.

  2. Coulomb's law: Coulomb's law states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. This means that if two charged particles are placed at a certain distance from each other, the force between them will be the same regardless of the system they are a part of. Thus, the net force on the system will always be zero.

  3. Symmetry: The net force on a system under electrostatic force is also zero because of the symmetry of the system. If there are multiple charged particles in a system, and they are arranged symmetrically, then the forces between them will cancel out, resulting in a net force of zero.



Therefore, the net force on a system under electrostatic force will always be equal to zero due to Newton's third law, Coulomb's law, and symmetry.

"the net force on system under electrostatic force will always be equa...
Electric force is conservative in nature . Work done by static electric field is independant of path taken by the charge . There is no change in voltage around any close path . When returning to starting point in a close path , net external work done is zoro . Since , work done = F × d . Hence , work done is zero , then force will also zero . Therefore , net force on system under electrostatic force will always be equal to zero .

Read the passage given below and answer the following questions:Some colloids are stable by their nature, i.e., gels, alloys, and solid foams. Gelatin and jellies are two common examples of a gel. The solid and liquid phases in a gel are interspersed with both phases being continuous. In most systems, the major factor influencing the stability is the charge on the colloidal particles. If a particular ion is preferentially adsorbed on the surface of the particles, the particles in suspension will repel each other, thereby preventing the formation of aggregates that are larger than colloidal dimensions. The ion can be either positive or negative depending on the particular colloidal system, i.e., air bubbles accumulate negative ions, sulphur particles have a net negative charge in a sulphur sol, and the particles in a metal hydroxide sol are positively charged. Accumulation of charge on a surface is not an unusual phenomenon-dust is attracted to furniture surfaces by electrostatic forces. When salts are added to lyophobic colloidal systems the colloidal particles begin to form larger aggregates and a sediment forms as they settle. This phenomenon is called flocculation, and the suspension can be referred to as flocculated, or colloidally unstable. If the salt is removed, the suspension can usually be restored to its original state; this process is called deflocculation or peptization. The original and restored colloidal systems are called deflocculated, peptized, or stable sols. Why does a small amount of salt have such a dramatic effect on the stability of a lyophobic colloidal system? The answer lies in an understanding of the attractive and repulsive forces that exist between colloidal particles. Van der Waals forces are responsible for the attractions, while the repulsive forces are due to the surface charge on the particles. In a stable colloid, the repulsive forces are of greater magnitude than the attractive forces. The magnitude of the electrical repulsion is diminished by addition of ionized salt, which allows the dispersed particles to aggregate and flocculate. River deltas provide an example of this behaviour. A delta is formed at the mouth of a river because the colloidal clay particles are flocculated when the freshwater mixes with the salt water of the oceanQ. When Van der Waals forces are greater than forces due to the surface charge on the particles,
