The electric potential due to an electric dipole at a point on the perpendicular bisector of the dipole axis is 0.
What is the value of electric potential at any point?
A spherical sphere of charge creates an external field just like a point charge, for example. 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.
When the electric potential at any point due to an electric dipole is maximum?
The potential at a point due to an electric dipole will be maximum and minimum when the angles between the axis of the dipole and the line joining the point to the dipole are respectively. V=pcosθr2. If θ=0∘ then Va=max. If θ=180∘ then Ve=min.
What is potential due to electric dipole?
An electric potential is the amount of work needed to move a unit positive charge from a reference point to a specific point inside an electric field without producing acceleration. A dipole is a pair of opposite charges with equal magnitudes separated by a distance, d.
What is the value of electric dipole?
… qd is defined as the electric dipole moment. Its magnitude indicates the maximum torque exerted upon a given electric dipole per unit value of the surrounding electric field in a vacuum. The electric dipole moment, a vector, is directed along the line from negative charge toward positive charge.
At what point the potential is maximum and minimum?
At lowest point of motion , potential energy is minimum . At higest point of motion , potential energy is maximum .
What are the points at which electric potential of a dipole has maximum value and minimum value?
(i) At axial points, the electric potential of a diople has maximum positive or negative value. (ii) At equatorial points, the electric potential of a dipole is zero.
How electric field and electric potential are related?
The relationship between potential and field (E) is a differential: electric field is the gradient of potential (V) in the x direction. This can be represented as: Ex=−dVdx E x = − dV dx . Thus, as the test charge is moved in the x direction, the rate of the its change in potential is the value of the electric field.
What is electric potential difference in simple words?
Electric potential difference, also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field. Electric potential difference is the change of potential energy experienced by a test charge that has a value of +1 .
Where does the electric potential due to electric dipole becomes zero?
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.
What is the formula for potential of a dipole?
3.4: Potential Energy of a Dipole in an Electric Field. P.E=−pEcosθ=−p⋅E. This is negative when θ is acute and positive when θ is obtuse.
