Where is electric potential greatest in a dipole?

The potential energy is lowest when the dipole is aligned with E and highest if it is anti-aligned. If the field is not uniform, then the magnitude of the electric force acting on the positive charge can be different from that acting on the negative charge, and there can be a net force acting on the dipole.

Where is electric potential the greatest?

(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.

Where is the electric field strongest in a dipole?

The pattern of the lines for the dipole indicates that the electric field is greatest in the region between and immediately surrounding the two charges, since the lines are closest together there.

How do you find the electric potential from a dipole?

Electric dipole moment is represented by a vector p of magnitude 2qa and this vector points in direction from -q to +q. To find electric potential due to a dipole consider charge -q is placed at point P and charge +q is placed at point Q as shown below in the figure.

In which figure is the potential energy of the electric dipole maximum?

Also, the potential energy of the dipole moment is maximum, that is [ + pE] when the angle between dipole moment [vec p] and electric field [vec E], is [pi ]. So, the correct answer is “Option C”.

How electric potential is created?

As combination of proton and Neutron gives +ve charge and electron -ve charge. Like gravitational force, nucleus (proton+neutron) having force which attract electrons. When +ve charge and -ve charge collected on two side of battery, it creates potential difference between two sides that is voltage.

What is the difference between electric potential and potential difference?

Electric Potential Energy and Potential Difference

Electric potential energy results from forces between charges; potential difference is the energy needed to move a charge from point A to B.

What happens to dipole in electric field?

Instead, on one surface the dipole heads create a positive surface charge, while at the opposite surface the dipole tails create a negative surface charge. These two opposite surface charges create a net electric field in a direction opposite to the direction of the dipoles.

Where is the electric field weakest in a dipole?

Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest. If the lines are uniformly-spaced and parallel, the field is uniform.

What is dipole in electric field?

A pair of electric charges with an equal magnitude but opposite charges separated by a distance d is known as an electric dipole. The electric dipole moment is a vector having a defined direction from the negative charge to the positive charge. …

How do you solve electric potential?

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.

Why is electric dipole moment important?

An electric dipole consists of 2 equal magnitude, opposite-signed charges. The physical significance is it gives a measure of the polarity/polarization of a net neutral system. If the dipole moment is small, either the charges are small or the separation is small.
