## What is the relationship between field strength and distance in electric potential graphs?

For a uniform field, the relationship between electric field (E), potential difference between points A and B (Δ), and distance between points A and B (d) is: **E=−Δϕd E = − Δ ϕ d** If the field is not uniform, calculus is required to solve.

## How does electric field and electric potential vary with distance?

Electric Potential V of a Point Charge Thus **V for a point charge decreases with distance**, whereas E for a point charge decreases with distance squared: E=Fq=kQr2 E = F q = k Q r 2 .

## What is the relationship between the field strength and the distance between the charges?

The strength of an electric field as created by source charge Q is **inversely related to square of the distance from the source**. This is known as an inverse square law. Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases.

## What is the formula of electric field due to dipole?

The electric dipole moment is the product of either of two charges (ignoring the sign) and the distance between them. A dipole is an arrangement of two charges bearing the same magnitude but an opposite polarity separated by some distance. 2a = dipole length (a vector quantity) **= displacement of – q charge w.r.t. + q.**

## What is the relation between electric field intensity and electric potential?

The relation is very simple. Electric field intensity is equal to the negative of rate of change of potential with respet to the distance or it can be defined as the negative of the rate of derivative of potential difference, **V with respect to r, E = – dV/dr.**

## How does distance affect magnetic field strength?

If the distance between two magnets with like poles gets smaller, then the **repelling force between them will get bigger**, because the force between two magnets gets stronger as they get closer together, and weaker as they get farther apart.

## What is the relationship between the electric field E and the electric potential V between the plates of the capacitor?

Electric field strength

In a simple parallel-plate capacitor, a voltage applied between two conductive plates creates a uniform electric field between those plates. The electric field strength in a capacitor is **directly proportional to the voltage applied and inversely proportional to the distance between the plates**.

## What is difference between electric field and electric force?

Electric charge is something that a particle/ object has due to excess/deficent charge present on it. Electric field is the magnitude of Electrostatic force experienced by an electricaly charged particle in space. Think of a field as “the effect something has which spreads out”.

## What is the relationship between force 12 and electric field?

The electric field E due to a point charge at a point is the **force F per unit charge** acting on a charged body of charge q placed at that point. The electric potential due to a point charge is the external work done to move a unit charge against the electric field by an infinitesimal distance without any acceleration.
