In summary, the conversation discusses the concept of representing a system of 3 unequal point charges located on the vertices of an equilateral triangle as a single point charge for the purpose of calculating the electric field intensity. It is mentioned that at large distances, the electric field approaches that of a point charge with the magnitude of the total charge. The possibility of deriving a general expression for the coordinates of the center of charge, similar to the center of mass, is also discussed.

if i have 3 unequal point charges located on the vertices of an equilateral triangle then can i assume the whole charge to be concentrated at one point to represent the whole system ? i.e one can assume the entire charge to be concentrated at that point for the purpose of calculating the electric field intensity ? can we derive a general expression for coordinates of center of charge like center of mass ?

The electric field of a collection of individual charges is the vector sum of the electric field of each charge.

At large distances, the electric field approaches that which would be given by a point charge of the magnitude of the total charge.

Yes - a coordinate system is a key part.

FAQ: Electric Field Intensity at Centre of Charge?

What is electric field intensity at the center of a charge?

The electric field intensity at the center of a charge is a measure of the strength of the electric field at that point. It is defined as the force per unit charge experienced by a small test charge placed at the center of the charge.

How is the electric field intensity at the center of a charge calculated?

The electric field intensity at the center of a charge can be calculated using the formula E = kQ/r^2, where k is the Coulomb's constant, Q is the magnitude of the charge, and r is the distance from the center of the charge.

Does the electric field intensity at the center of a charge depend on the charge's magnitude?

Yes, the electric field intensity at the center of a charge is directly proportional to the magnitude of the charge. This means that an increase in the charge's magnitude will result in an increase in the electric field intensity at the center.

How does the distance from the charge affect the electric field intensity at the center?

The electric field intensity at the center of a charge is inversely proportional to the square of the distance from the charge. This means that as the distance increases, the electric field intensity at the center decreases.

What is the direction of the electric field at the center of a charge?

The electric field at the center of a charge is always directed away from the charge if it is positive and towards the charge if it is negative. This is in accordance with the principle that like charges repel and opposite charges attract.
