When is the torque on an electric dipole in an electric field is maximum?
The torque on an electric dipole in an electric field is maximum when the dipole is aligned parallel or anti-parallel to the electric field lines. This occurs because the torque is given by the cross product of the electric dipole moment vector and the electric field vector, and it is maximum when the angle between them is 90 degrees.
You turn an electric dipole end for end in a uniform electric field.How does the work you do depend on the initial orientation of the dipole with respect to the field?
The work done by you to turn the electric dipole end for end in a uniform electric field depends on the initial orientation of the dipole with respect to the field. If the dipole is initially oriented such that its positive and negative charges are parallel to the electric field, then no net work is done as the electric field does not do any work on the dipole as the electric field lines do not transfer any energy. On the other hand, if the dipole is initially oriented such that its positive and negative charges are perpendicular to the electric field, then work is done by you to turn the dipole as the electric field exerts a force on the charges in the dipole in opposite directions, causing them to move in opposite directions. As a result, you have to do work to move the charges and turn the dipole.
What is the work done in rotating a electric dipole in uniform electric field from parallel position to anti-parallel position?
The work done in rotating an electric dipole in a uniform electric field from parallel position to anti-parallel position is zero. This is because the torque applied to rotate the dipole is perpendicular to the direction of the electric field, so the work done is zero.
How electric field is equal to force by dipole moment?
The electric field produced by a dipole at a distance is given by the formula E = 2kP/r^3, where k is the electrostatic constant, P is the dipole moment, and r is the distance from the dipole. This electric field exerts a force on a test charge q placed in the field, given by F = qE. Therefore, the force on a charge due to a dipole moment is directly proportional to the dipole moment and the charge, according to these equations.
What electric field parallel or anti parallel to the electric dipole?
An electric field parallel to an electric dipole will exert a torque on the dipole, causing it to align with the field. An electric field anti-parallel to an electric dipole will also exert a torque on the dipole, causing it to rotate and align with the field in the opposite direction.
When is the torque on an electric dipole in an electric field is maximum?
The torque on an electric dipole in an electric field is maximum when the dipole is aligned parallel or anti-parallel to the electric field lines.

What is the angle between dipole moment and electric field in a electric dipole?
The angle between the dipole moment and the electric field in an electric dipole is 0 degrees or 180 degrees. This means the dipole moment is either aligned with or opposite to the electric field direction.
An electric dipole placed with its axis inclined at an angle to the direction of a uniform electric field experiences?
It experiences a torque but no force. As the dipole is placed at an angle to the direction of a uniform electric field it experiences two opposite and equal forces which are not along the same line. This develops a torque which aligns the dipole along the field. The dipole does not experience any force as the two forces cancel each other.
What electric field parallel or anti parallel to the electric dipole?
An electric field parallel to an electric dipole will exert a torque on the dipole, causing it to align with the field. An electric field anti-parallel to an electric dipole will also exert a torque on the dipole, causing it to rotate and align with the field in the opposite direction.
Why the direction of dipole moment of electric dipole is taken from negative to positive charge?
The direction of the dipole moment of an electric dipole from negative to positive charge is chosen as a convention to align with the direction of the electric field produced by the dipole. This convention allows for easy calculation and understanding of how the dipole interacts with external electric fields.
An electric dipole is placed in a nonuniform electric filedIs there a net force on the dipole?
yes, there is a NET field .electric dipole experiences a net field .(not in uniform E.Field)
What is two opposite electric charges separated by a short distance called?
Two opposite electric charges separated by a short distance are called an electric dipole.
Two point charges plus q and -q are held some distance apart what are the points at which the resultant field is parallel to the line joining the two charges?
The system of two point charges plus q and -q constitutes an electric dipole.In the case of an electric dipole ,the resultant field is parallel to the line joining the two charges at 1.any point on the line joining the charges 2.any point on the perpendicular bisector of the line joining the two charges.
Derive the expression for electric potential as line integral dueto charge distribution and due to adipole?
The electric potential due to a charge distribution can be obtained by integrating the electric field over the path from infinity to the point of interest. This is given by the line integral of the electric field, V = -∫ E ⋅ dl. For a dipole, the electric potential can be derived by considering the potential contributions from both the positive and negative charges of the dipole. The expression for the electric potential due to a dipole is given by V = k * p ⋅ r / r^3, where k is the Coulomb constant, p is the dipole moment, r is the position vector pointing from the charge to the observation point, and the dot product signifies the cosine of the angle between p and r.
