The electric field and the potential of an electric dipole vary with distance r as
Electric field and electric potential at a general point at a distance r from the centre of the dipole is
An electric dipole is placed at the centre of a hollow conducting sphere. Which of the following is correct?
When electric dipole is held in the sphere, electric field is not zero anywhere on the sphere. However, net electric flux through the sphere is zero.
Which of the following is not true?
The electric dipole potential varies as 1/r at large distance is not true.
The distance between H + and Cl − ions in HCl molecules is 1.38 Å. The potential due to this dipole at a distance of 10Å on the axis of dipole is
Here, 2a = 1.38 × 10−10m, r = 10 × 10−10 m charge, q = 1.6 × 10−19C
Four points a, b, c and d are set at equal distance from the centre of a dipole as shown in the figure.
The magnitudes of electrostatic potential Va, Vb, Vc and Vd would satisfy the following relation
Vb = 0
∴ Va = Vc > Vb = Vd
