What will be value of electric field at the Centre of electric dipole?
Answer: Twice the electric field.
Is the electric field in the middle of a dipole zero?
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 is electric field intensity at the midpoint of electric dipole?
In the middle of the dipole, the electric fields contributed by both charges are in the same direction; they are both pointing toward the negative charge. Thus, the magnitude of the electric field is the sum of the contribution of the two charges. E=kqa2+kqa2=2kqa2.
Where is the electric field zero in a dipole?
There is a spot along the line connecting the charges, just to the “far” side of the positive charge (on the side away from the negative charge) where the electric field is 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.
What is Centre of the 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. Hope it helps you.
Will the electric field always be zero at any point where the electric potential is zero?
(a) No, just because the electric field is zero at a particular point, it does not necessarily mean that the electric potential is zero at that point. … At the midpoint between the charges, the electric field due to the charges is zero, but the electric potential due to the charges at that same point is non-zero.
Will the electric potential be zero at a point if electric field intensity is zero at that point?
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.
Why is the electric field never zero for a dipole?
Originally Answered: Why is the electric field for an electric dipole not zero? Direction of electric field is from positive to negative. Since the difference potential difference between dipole is not zero therefore there is electric field between them.
What is the electric field at midpoint?
Therefore, the electric field at mid-point O is 5.4 × 106 N C−1 along OB. (b) A test charge of amount 1.5 × 10−9 C is placed at mid-point O. The force is directed along line OA. This is because the negative test charge is repelled by the charge placed at point B but attracted towards point A.
What is the electric field intensity?
The electric field intensity at a point is the force experienced by a unit positive charge placed at that point. Electric Field Intensity is a vector quantity. … Formula: Electric Field = F/q.
What is electric field intensity class 12?
Electric field intensity: the electric intensity at any point in an electric field is defined as the electric force per unit positive test charge placed at that point i.e. … Electric field strength at midpoint of dipole: the electric field strength at midpoint $C$due to charge $ + q$is $ – q$along the same direction.
