What are the magnitude and direction of the electric field?
at point P, between both charges. Wanted : The magnitude of the electric field is zero located at…. Charge A is positive so that the direction of the electric field points away from charge A (to the right). Charge B is positive so that the direction of the electric field points away from charge B (to the left).

What is point charge electric field?
The electric field of a point charge is, like any electric field, a vector field that represents the effect that the point charge has on other charges around it. The effect is felt as a force, and when charged particles are not in motion, this force is known as the electrostatic force.
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 field dipole?
The formula for electric dipole moment for a pair of equal & opposite charges is p = qd, the magnitude of the charges multiplied by the distance between the two.
What do you mean by dipole field?
Dipole fields, or an electric field between two charges of the same but opposite strength, work in a similar way to the poles on the rock. When two charges with equal but opposite charges are placed near each other, a field with curved lines is created.
What is the charge of dipole?
An electric dipole deals with the separation of the positive and negative charges found in any electromagnetic system. A simple example of this system is a pair of electric charges of equal magnitude but opposite sign separated by some typically small distance. (A permanent electric dipole is called an electret.)
What is an electric dipole give two examples?
Physical significance of dipoles – definition Therefore, their dipole moment is zero. CO2 and CH4 are of this type of molecules. Therefore they have a permanent electric dipole moment, even in the absence of an electric field. Such molecules are called polar molecules. Water molecules, H2O,is an example of this type.
What is the net charge of an electric dipole?
An electric dipole is a type of electric charge distribution which contains two point charges, one positive and one negative. The two charges in a dipole have the same magnitude, so the net charge of the dipole is zero. An electric dipole is a combination of two point charges having equal magnitude but opposite signs.
What is an example of ideal electric dipole?
– An ideal dipole consists of two very very large charges + q and -q seperated by a very very small distance. – An ideal dipole has almost no size. – Molecules are made up of positive and negative charges seperated by small distances like water, ammonia etc and they act as electric dipoles.
What is ideal electric field?
A pair of equal and opposite charges seperated by a small vector distance is called an electric dipole. An ideal dipole consists of two very very large charges + q and – q seperated by a very very small distance. An ideal dipole has almost no size.
Can the electric field by a small dipole be zero at a finite distance from electric dipole?
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.
What is the net force on a dipole in a uniform electric field?
The net force acting on a dipole placed in a uniform electric field is zero. The forces on the two charges constituting the dipole are equal and opposite. Hence, the net force is zero.
