A point electric dipole with dipole moment .p. is placed in the external uniform electric field whose strenght is E_(0) with .p. parallel to E_(0). Then

Answer»

Net FORCE EXPERIENCED by the dipole is zero
One of the equi-potential surface ENCLOSING the dipole forms sphere
The radius of SPHERICAL euqi-potential `[(P)/(4piepsilon_(0)E)]^((1)/(3))`
The radius of spherical equi-potential surface is `SQRT((P)/(4piepsilon_(0)E))`
