Question

The electric potential at distance b which is situated at a distance x

Answer 1

Answer:

The equation for the electric potential due to a point charge is V=kQr V = kQ r , where k is a constant equal to 9.0×109 N⋅m2/C2.Therefore, the electric potential due to the point charge at a given point relative to a zero at an infinite distance away decreases with where a is the distance from the charge to the reference point. As a increases, the potential from a to infinity will decrease.

Answer 2

The electric field generated by non moving charges, is called electrostatic field. The electrostatic field is conservative, therefore, as with other conservatives fields it is possible to define a potential function   ϕ  whose gradient characterizes the field at a particular point in space. The potential function, unlike the electric field, is a scalar value and only the potential difference has a physical meaning. To define the value of the electrostatic potential at a specific point we need to specify a reference where the potential is assumed to be zero. Usually the zero potential reference is at an infinite distance from the charges generating the field.
