Why is the electrostatic potential due to an electric dipole at an equatorial point zero?
Because it takes no work to bring a test charge in from infinity along the
perpendicular bisector of the dipole (any line in the equatorial plane).
At least, that's true for any distance that's much greater than the separation
of the two charges that make up the dipole. In that case, the potential is
proportional to cos(angle between the line joining the charges and the direction
from its midpoint to the test charge). That's the angle that's 90 degrees in the
equatorial plane, and its cosine is zero.

What kind of force is a dipole dipole of force?
Dipole-dipole interactions are of electrostatic nature.
How much work is done in rotating a dipole from stable to unstable equillibrium?
In rotating a dipole from stable to unstable equilibrium, the work done is equal to the change in potential energy. As the dipole is moved, the electrostatic potential energy of the system changes, resulting in work being performed on the dipole. The amount of work done is equal to the difference in potential energy between the two equilibrium positions.
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 is the angle between the electric dipole moment and the electric field strength due to it on axial line?
The angle between the electric dipole moment and the electric field strength on the axial line is 0 degrees (or parallel). This is because on the axial line, the electric field points in the same direction as the electric dipole moment, resulting in the minimum potential energy configuration for the dipole.
What is the work done in moving a test charge q through a distance of 1 cm along the equatorial axis of an electric dipole and why?
No work is done in moving a test charge along the equatorial axis of an electric dipole because the force acting on the charge is perpendicular to the direction of motion. As a result, the work done by the electric field is zero because the force and displacement are orthogonal.
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.

Which orientation of an electric dipole in a uniform electric field would correspond to stable equilibrium?
when angle 0 b/w dipole moment vector p and electric field vector E is zero then potential energy of dipole, U=-pEcos0 =-pE and torque=pEsin0=0;which means that the electric dipole is in stable equilibrium.
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.
What happened when an electric dipole is held in non uniform electric field?
When an electric dipole is held in a non-uniform electric field, the dipole experiences a net torque causing it to align itself in the direction of the field. The dipole will tend to orient itself with its positive end facing towards the direction of the field and its negative end facing away from it. This alignment leads to a potential energy change in the dipole, with the dipole experiencing a force due to the non-uniform field.
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.
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.
