# What is the torque on a dipole in an electric field maximum?

Contents

Maximum torque is at 90 degrees.

## What is the torque on a dipole in a field maximum?

When an electric dipole moment is kept in an electric field, force acts on both charges in a dipole. The force acting on the charges acts as a couple and the dipole experiences a torque. The torque is maximum when it makes [{{90}^{o}}] with the electric field, which is the most unstable position.

## What is the torque on a dipole in an electric field?

An electric dipole in an electric field that is external is subjected to a torque written as τ = pE sin θ where symbol θ is the angle which is between p and E. The torque tends to align the moment of the dipole p in the direction of E.

## On which condition does the torque acting on electric dipole is maximum?

Torque will maximum when value of sinθ will be maximum or θ=90o.

## When electric dipole is maximum?

When the angle between the dipole moment and electric field is 180° then the potential energy of electric dipole is maximum.

## At what angle the torque acting on a electric dipole placed in uniform electric field is maximum and what is maximum value?

Thus Torque is Maximum only if the angle between the P and E is Maximum i.e, Sin@ has to be Maximum…and Sin@ is maximum only if @ = 90 degree… So Torque is maximum on Dipole if angle between P amd E is 90 degree….

## In which condition torque acting on dipole is maximum and minimum?

Case 1: When Ɵ is 90 then Torque is maximum and is equal to pE which means the dipole moment should be perpendicular to the direction of the uniform electric field E. Case 2: When Ɵ is 0, then Torque is minimum.

## What is the formula of torque in electric field?

Show that the torque on an electric dipole placed in a uniform electric field is. τ =P. ×E.

## How does a 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.

## When an electric dipole is held at an angle?

Answer: the forces experienced by the 2 charges constituting the electric dipole when placed in an uniform external electric field are equal and opposite in nature, the net force on the dipole is zero. No torque act on the dipole when the moment of electric dipole is parallel to the electric field.

## When an electric dipole is held at an angle in a uniform electric field?

1) the forces experienced by the 2 charges constituting the electric dipole when placed in an uniform external electric field are equal and opposite in nature, the net force on the dipole is zero. No torque act on the dipole when the moment of electric dipole is parallel to the electric field.

## Under what condition will the torque become maximum?

Torque is defined as τ = rF sin θ, where F is the force, r is the distance from the pivot that the force is applied, and θ is the angle between r and F. … (b) The maximum torque occurs when θ is a right angle and sin θ = 1. (c) Zero (minimum) torque occurs when θ is zero and sin θ = 0.
