## How does the electric potential at a point due to an electric dipole vary with distance measured from its Centre compare the same for point charge?

Electric potential is **inversely proportional to the square of the distance from the centre** of the dipole (i.e. V ∝ 1 r 2 ). Where as the potential due to point charge is inversely proportional with the distance from the charge (i.e. V ∝ 1 r ).

## How does the electric potential at a point due to an electric dipole vary with distance?

Explanation: For an electric dipole (at large distances), The electric **potential varies inversely with the square of the distance**. For a point charge, The electric potential varies inversely with the distance.

## How does electric potential vary with distance?

Actually, **electric potential decreases as you move farther from a charge distribution**. … That’s because like charges repel each other, so it takes more and more energy to move the charges together the closer you get.

## What is the relation of potential of electric dipole and distance r?

(where p is the dipole moment, r(≫2a) is the distance at which the potential V of the dipole is calculated and θ is the angle between the distance vector and the dipole.) A. **V=pcosθ4πε0r4**. B.

## How does the electric field and electric potential vary with distance from a point charge Class 12?

Electric Potential V of a Point Charge

The potential at infinity is chosen to be zero. 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 .

## How does the electric field varies for a dipole with respect to distance?

Along axis of dipole (Point Q)

Compared to a point charge which only decreases as the inverse of the square of the distance, the dipoles field **decreases much faster** because it contains both a positive and negative charge.

## How does the electric field at a point vary with distance r due to a point charge and due to a short dipole?

The electric field varies **inversely as the square of the distance from the point charge**.

## Does potential difference change with distance?

Moving towards and away from the charge results in change of potential; **the relationship between distance and potential is inverse**. For one point charge, potential will be constant for all points a certain radial distance away.

## How does the potential depend upon distance from a charge?

As you move away from the charge, as the distance from the charge increases, the **potential becomes less positive**, and decreases getting closer and closer to zero.

## What happens to the electric potential energy if the distance between the source charge and the test charge is tripled?

**A doubling of the separation distance between two** point charges results in a quadrupling of the electric force. A tripling of the separation distance between two point charges results in an electric force which is one-sixth of the original value.
