Question

Equipotential spheres are drawn round a point charge. As we move away from charge will the spacing between two spheres having a constant potential difference decrease, increase or remain constant.

Answer 1

Answer:

the potential of the equipotential surfaces decreases

Explanation:

                     from the formula

                                              v is inversely proportional to the radius

Answer 2

Given :

Equipotential sphere drwan round a point charge.

To find :

Variation of spacing on moving away.

Solution :

Electric Potential for a Point Charge :

A point charge is an object like a small charged ball. Such objects contribute to

both electric field and electric potential in the space around them. The contribution of an

object of charge Q to electric potential at point a distance r away is given as :

$\bf V = \frac{kQ}{r} \:$

The potential outside a charged sphere that

has a spherically symmetric charge distribution where Q is the total charge on the sphere .

r is the distance from center of sphere to a point outside the

sphere.

In a two-dimensional diagram of this situation, the equipotential lines are circles centered on

the equipotential lines are circles centered on the object.

The potential difference (which is more

important than value of potential at a point) between one equipotential line and the next line is a constant value, but that lines get further apart as you move away from the object because the field decreases the farther you are from the object, the smaller its influence.
