When the angle between the dipole moment and electric field is 180° then the potential energy of electric dipole is maximum. (II). When the angle between the dipole moment and electric field is zero then the potential energy of electric dipole is minimum.
What are the points at which the electric potential of a dipole has maximum value?

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 .
At which point electric potential is maximum?
In the case of an equipotential surface, the electric field at every point is always normal (to the direction of the electric field (E)). Therefore, the potential at point B is more than C and B. So, the potential at points are VB>VC>VA. Hence, the electric potential at point B is maximum.
At which position the potential energy in an electric dipole is maximum when it is in an electric field?
The potential energy is maximum when the dipole is aligned anti-parallel (θ = π) to the external electric field and minimum when the dipole is aligned parallel (θ = 0) to the external electric field.
What are the points at which electric potential?
The electric potential tells you how much potential energy a single point charge at a given location will have. The electric potential at a point is equal to the electric potential energy (measured in joules) of any charged particle at that location divided by the charge (measured in coulombs) of the particle.
What are the points at which electric potential of a dipole has i maximum Vale II 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.
Is electric potential on dipole axis maximum?
The electric potential will be maximum at the dipole axis. … The electric potential will be zero at the perpendicular axis of the dipole.
At what point in the pendulum is the potential energy maximum?
Next, let’s consider tangential acceleration. When the pendulum reaches its highest point, it will briefly be at rest for a very short instant. At this highest point, the pendulum also has its greatest amount of potential energy. When the pendulum begins to fall, the force due to gravity causes the pendulum to fall.
What is the potential at a point due to a positive charge of 100μc at a distance of 9m?
V = 10^5 V
Therefore, electric potential due to charge is 10^5 V.
Where is the electric potential greater?
(For the same charge, the electric potential is greatest at locations of higher potential energy.) (The + charge is moving with nature; work is not required when it moves with the E field.) (When a + charge moves naturally in the direction of the E field, it is moving from high PE to low PE.
How does electric potential vary from point to point?
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 .
What is the potential at the center of the square?
The potential at the center of the square is the sum of the potentials due to the four individual charges. The potential due to a point charge depends on the magnitude of the charge and the distance from the charge.
