What is the value of electric field at the Centre of a dipole?
Therefore, electrical field at point p is the question mark. Since the total distance between the charges is d and this point is the center of the dipole, therefore this distance will be equal to d over 2.
What is the electric field at the Centre of an electric dipole?
The electric dipole moment, in the case of a simple electric dipole, points from the negative charge to the positive charge and has a magnitude equal to the strength of each charge multiplied by the distance between the charges. Using the equation, we can calculate the electric field created by a point charge.
Why is the electric field inside a conductor zero?
Due to a large number of electrons, the force of repulsion acting in between them is also very high. Hence in order to minimize the repulsion between electrons, the electrons move to the surface of the conductor. Hence we can say that the net charge inside the conductor is zero.
When an electric dipole is placed in a uniform?
Even if we change the orientation, the length and the charge of the dipole, the net force on the dipole will be equal to zero. Hence, the electric force on a dipole when it is placed in a uniform electric field is always zero.
What is electric field intensity?
A measure of the force exerted by one charged body on another. Imaginary lines of force or electric field lines originate (by convention) on positive charges and terminate on negative charges.
Is electric potential zero when electric field is 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.
Can electric field due to a dipole be zero?
Answer. If dipole moment p is zero, then E=0,but then there is no dipole which is simply defined as two equal and opposite point charges separated by finite distance. This is not possible and hence field of a dipole is not zero.
Is it possible to have a zero electric field value between?
7) Is it possible to have a zero electric field value between a negative and positive charge along the line joining the two charges? … Yes, regardless of the magnitude of the two charges. C) No, a zero electric field cannot exist between the two charges.
