1: An electric dipole and its corresponding dipole vector, →p. … 3, the net force on the dipole is zero because the force on the positive charge will always be equal and in the opposite direction from the force on the negative charge. Figure 16.4.
Why electric field of a dipole is not zero?
6 Answers. Dipole consists of two charges – one positive charge and one negative charge. Those two charges are not at the same point in space. That means that they give some nonzero electric field in total.
Can an electric field be zero?
For like charges, the electric field will be zero closer to the smaller charge and will be along the line joining the two charges. For opposite charges of equal magnitude, there will not be any zero electric fields.
What is the electric field of a dipole?
Answer: We know that when a system is subjected to an external field, the net dipole moment generates in its direction. Therefore, the space around it in which the electric effect of the dipole can be experienced is called the field of an electric dipole or the dipole field.
Is electric potential zero when electric field is zero?
1. (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.
Under which condition electric intensity at a point is zero but electric potential is not zero?
So there is the answer. The electric potential at the midpoint between the two +Q charges where the electric field is zero is nonzero and negative.
How does dipole behave in electric field?
In an electric field a dipole undergoes a torque, tending to rotate so that its axis becomes aligned with the direction of the electric field. … The electric dipole moment, a vector, is directed along the line from negative charge toward positive charge.
What happens when an electric dipole is placed in a non uniform electric field?
If an electric dipole is placed in a nonuniform electric field, then the positive and the negative charges of the dipole will experience a net force. And as one end of the dipole is experiencing a force in one direction and the other end in the opposite direction, so the dipole will have a net torque also.
Can electric field be negative?
Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field. For a positive charge, the force is along the field.
At which point or points is the electric field zero?
The electric field is zero at two points along the x axis; one such point is to the right of the -2q charge and the other is to the left of the +4q charge. 2.
