Best answer: What will be the value of electric potential at the Centre of the electric dipole?

What is the electric potential at the center of a dipole?

Potential at the center of an electric dipole is zero.

What is the value of electric field at the Centre of electric dipole?

Answer: Twice the electric field.

Why electric potential at the Centre of a dipole is zero?

Answer 0. This is because the force exerted on the charge Q by the electric field between Q1 and Q2 is always perpendicular to the displacement of the charge in going from A to B. That means zero work is done.

What will be the potential due to the dipole on the midpoint of the two charges?

Explanation: The potential due a dipole at a point P will be V = m cos θ/(4πεr2). Now it is given that potential on the midpoint, which means P is on midpoint, then the distance from midpoint and P will be zero.

IT\'S FUNNING:  Does an electric fireplace insert need to be vented?

What is the center of a dipole?

Answer: The electric field at centre of the dipole is equal to twice the electric field produced by any one of the charge an this dipole at the centre and it act long positive to negative charge.

What is the electric potential at point a?

The electric potential at point A is 3137.46 V. b. The potential energy of a proton at point A is 5.020 × 1016J.

What are the electric field and electric potential at the midpoint of a dipole system?

A good example is the case of a dipole, which is two charges of the same magnitude, but opposite sign, separated by some distance. At the midpoint between the charges, the electric potential due to the charges is zero, but the electric field due to the charges at that same point is non-zero.

What will be the electric field at O if the charge q at a is replaced by Q?

If the charge q at A is replaced by -q, it is equivalent to adding charge -2q at A. Therefore, electric field at O, E2=2q4πε0r2 along OA.

Where does electric potential equal zero?

The electric potential from a single charge is defined to be zero an infinite distance from the charge, and the electric potential associated with two charges is also defined to be zero when the charges are infinitely far apart.

Is it possible for the electric potential at a point to be 0 V and for the electric field at that point to be non-zero explain?

Yes, electric potential can be zero at a point even when the electric field is not zero at that point.

Is electrostatic potential necessarily zero at a point where electric field is zero?

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.

What is the voltage at the midpoint of the dipole?

Now, make an electric dipole by replacing one of the positive charges with a negative charge, so the final configuration looks like the figure shown below. What is the voltage at the midpoint of the dipole? zero.

What is the expression for electric dipole moment?

An electric dipole is formed by two point charges +q and −q connected by a vector a. The electric dipole moment is defined as p = qa .

What does dipole moment depend on?

Dipole moments occur when there is a separation of charge. … The larger the difference in electronegativity, the larger the dipole moment. The distance between the charge separation is also a deciding factor into the size of the dipole moment. The dipole moment is a measure of the polarity of the molecule.
