An electric field is a force per unit charge and an electric potential is an energy per unit charge. … Yes, electric potential can be zero at a point even when the electric field is not zero at that point. Considering the case of the electric dipole will help us understand this concept.
Can the electric potential at a point b0y electric field is non zero justify?
The short answer is YES. The potential can be non-zero at a point in a field where the field intensity is zero.
Can electric potential at a point with zero but not the electric field give example?
Yes, it is possible. Example : 1. Inside uncharged spherical shell and charged conductor electric field is zero but electric potential cannot zero.
Is the electrostatic potential necessarily zero at a point?
Electrostatic Potential and Capacitance
Electric potential necessarily need not be 0 if the electric field at that point is zero. For instance, at a point mid-way between two equal and similar charges, the electric field strength is zero but the electric potential is not zero. A charge of 8 mC is located at the origin.
Can there be electric potential at a point with zero electric field strength?
Yes, There can exist potential at a point where with zero electric intensity is zero. (1)Between two similar charges intensity of electric field is zero. … (2) Inside the charged spherical conductor electric field intensity is zero but potential is not zero.
Can electric field be zero and potential is not zero?
Yes, electric potential can be zero at a point even when the electric field is not zero at that point. … At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential is zero.
Under which condition electric potential at a point is zero but electric intensity is not zero?
So there is the answer. The electric potential at the midpoint between the two +Q charges where the electric field is zero is nonzero and negative.
Can an electric field be zero?
For like charges, the electric field will be zero closer to the smaller charge and will be along the line joining the two charges. For opposite charges of equal magnitude, there will not be any zero electric fields.
What does it mean if electric potential is zero?
What zero potential means, roughly, is that the charges in your system have cancelled out. For example exactly half way (or otherwise equidistant from them) between two equal and oppositely charged point charges, potential is zero.
Is the electrostatic potential necessarily zero at a point where the electric field strength is zero give example to justify your answer?
so, even if electric field at a point is zero, the potential may have some non zero constant value at that point. Example. Electric fied inside a charged conduting sphere is zero but potential at any point inside the sphere is same as that on the surface of sphere.
Why is the electric potential of earth is taken to be zero?
While the atmosphere of the earth consists mainly of positive ions. So there must be a potential gradient set up between the atmosphere and the surface of the earth. So the charge distribution over the whole of earth is zero.
Is a zero potential point necessarily has zero intensity?
Electric intensity at a point is the negative of rate of change of the electric potential at a point. So if a function is zero at a given point, the slope will not necessarily be zero.
