Best answer: What is couple in electric field?

What is couple in electric dipole?

(1) A pair of opposite charges separated by a small distance is called dipole. (2) Consider the charge of dipole are –q and +q coulomb and the distance between them is 2a. (3) Then the electric dipole moment P is given by P = q × 2a = 2aq. … (6) These two equal and opposite charges constitute torque or moment of couple.

What is a couple in physics?

couple, in mechanics, pair of equal parallel forces that are opposite in direction. … The turning effect, or moment, of a couple is measured by the product of the magnitude of either force and the perpendicular distance between the action lines of the forces.

What is couple give example?

A couple consists of two parallel forces that are equal in magnitude, opposite in direction and do not share a line of action. It does not produce any translation, only rotation. The resultant force of a couple is zero. example:opening of a door.

What is moment and couple?

Moment of the Couple

The tendency of a force is to rotate a body. It is measured by the moment of the force. The product of one of the two forces of a Couple and the perpendicular distance between their lines of action (called the arm of the Couple) is called the Moment of Couple.

What is the couple for a dipole moment?

(1) A pair of opposite charges separated by a small distance is called dipole. (2) Consider the charge of dipole are -q and +q coulomb and the distance between them is 2a. (3) Then the electric dipole moment P is given by p=q×2a=2aq. It is a vector.

What is a couple for a dipole moment write the value of net force of it?

The forces on the two charges constituting the dipole are equal and opposite. Hence, the net force is zero.

What is a couple in engineering?

A couple is a pair of forces, equal in magnitude, oppositely directed, and displaced by perpendicular distance or moment. The simplest kind of couple consists of two equal and opposite forces whose lines of action do not coincide.

Is couple and torque are same?

Torque vs Couple

The turning effect produced by a force on a body is called torque. It is calculated as force multiplied by perpendicular distance. A couple is a special case when there are two equal but opposite forces acting on a body that rotate it.

What is the formula of couple?

[M−1L2T−2]

What is couple give example and its uses?

Example: Children sitting on a see-saw. Their weights are the example of parallel forces. If there are two forces which are equal and opposite they form a couple. Couple: When two forces of equal magnitude opposite in direction and acting along parallel straight lines, then they are said to form a couple.

What is couple and its characteristics?

A couple is a pair of forces, equal in magnitude, oppositely directed, and displaced by perpendicular distance or moment. The simplest kind of couple consists of two equal and opposite forces whose lines of action do not coincide.

What do you mean couple?

1a : two persons married, engaged, or otherwise romantically paired. b : two persons paired together The people were lined up in couples. 2 : pair, brace needed a couple of bookends. 3 : something that joins or links two things together: such as.

How many is a couple of?

A couple: Everyone seems to agree that “a couple” means two. If you have a couple of options, you can safely assume that you will have to choose between A and B, and only A and B. A Few: Here’s where things tend to get confusing. I’ve asked different people how many they thought the words “a few” referred to.

What is arm of couple?

Answer: When two forces of equal magnitude opposite in direction and acting along parallel straight lines, then they are said to form a couple. The perpendicular distance between the two force forming a couple is called the arm of the couple.
