What is the orientation of electric dipole in electric field for unstable equilibrium?

-The dipole is in unstable equilibrium when it is oriented anti-parallel to the electric field (i.e. the angle between the dipole moment and the electric field is 180∘).

In which orientation dipole is in unstable equilibrium?

A dipole placed in a uniform electric filed is in Stable equilibrium when the electric field is directed along the direction of the dipole i.e., when is parallel to. Unstable equilibrium when the electric filed is directed at an angle of 180 degrees with the direction of the dipole, i.e., when is anti-parallel to.

Which position of dipole is known as stable and unstable equilibrium?

Note: Stable equilibrium means the lowest potential energy at the equilibrium point. Therefore the stable equilibrium the torque should be zero and the potential energy of the dipole should be minimum. Whereas the unstable equilibrium torque will be zero and the potential energy should be maximum or positive.

Which orientation of an electric dipole would correspond to stable equilibrium?

Which orientation of an electric dipole in a uniform electric field would correspond to stable equilibrium? When the direction of the electric dipole moment is aligning in the same direction as that of the Electric field the dipole is said to be in a stable equilibrium.

What is the condition for dipole to be in stable equilibrium unstable equilibrium?

The moment of the dipole is directed between -ve charge and + charge. Net force and torque on the system should be zero in equilibrium. Therefore, if Potential Energy is high, the equilibrium will be unstable, and equilibrium will be stable for minimum Potential Energy.

What will happen if an electric dipole is placed in 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.

At what position is the electric dipole in uniform electric field?

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.

When electric dipole is unstable?

-The dipole is in unstable equilibrium when it is oriented anti-parallel to the electric field (i.e. the angle between the dipole moment and the electric field is 180∘). Note: Assume that a dipole is formed by two charges, –q at A and +q at B, separated by a distance r.

GOOD TO KNOW:  What is a characteristic of renewable energy?

What is the angle in unstable equilibrium in uniform electric field?

In unstable equilibrium, the dipole is making an angle of 180o with the electric field and will have maximum potential energy.

What is the main condition of electric dipole in a body?

An electric dipole whose size is very small or negligible is called an ideal dipole. A dipole is said to be ideal if it’s charge is very large (q tends to infinite) and separation is very small (2l tends to zero).

Why do electric field lines never cross each other?

Electric field lines always point in one direction, at any point. When two lines intersect each other, tangents are drawn at that point indicating two directions of electric field lines, which is impossible therefore electric field lines cannot cross over each other.

What orientation of an electric dipole in a uniform electric field corresponds to its i stable equilibrium II unstable equilibrium?

(2)When the dipole is aligned anti-parallel to the electric field (i.e. the angle between dipole moment and the electric field is 180o), then the dipole is in unstable equilibrium.
