Question

A water molecule has a permanent electric dipole moment of magnitude 6 x 10^-30 C-m. estimate the size of the electric field produces at the position of a neighbouring water molecule which is 3 x 10^-9 m away

Answer 1

FOR SHORT DIPOLE ,THERE IS AN EQUATION
TO FIND THE ELECTRIC FIELD AT A POINT

E=kP squareroot(1+3cos2 θ)
r3


(where p=dipole moment
r =distance from dipole to the point at
which electric field is to be found out ,
θ is the angle between the dipole
moment and the distance vector )
p is given
r is given

and the dipole moment of one watermolecule makes an angle 0 with the distance vector

on solving ,you get the answer to be 4x106N/C
