What is the elecrostatic potential due to an electric dipole at an equatorial point?

Electric dipole moment, p = 4 × 10−9 C m Angle made by p with a uniform electric field, θ = 30° Electric field, E = 5 × 104 N C−1 Torque acting...

(d) In a nonuniform electric field, the dipole will experience a torque as well as a translational force.

(a) increases

(a) is always zero 

The correct answer is None.

(d) The torque on the dipole due to the field may be zero.

At every point on equatorial axis, the potential is zero, so work done W = qΔV = 0(zero).

P = 3 x 10-8cm ; E =104N/C  At stable equilibrium (θ1 ) = 0°  At unstable equilibrium (θ2) =180°  Work done in rotating dipole is given by:  W = PE (cosθ1 - cosθ2 )   =...

Dipole moment P =5 x10-4Cm. Electric field (E) =104N/C At stable equilibrium θ1 = 0° At unstable equilibrium θ2 =180° Work done = - PE (cosθ2 - cosθ1) = -(5 x 10-8 ) (104 )...

Dipole moment of an electric dipole is the product of either of charge and the length of dipole. It is a vector quantity. vector P = q(2vector a)
