NaCl when placed in a uniform electric field 20VM^-1 , both Na^+ and Cl^- ions experience a force (average distance between Na^+ and Cl^- is 1.3A). Br In what way the NaCl will orient in the electric field.

In a NaCl molecule there is an attractive force between Na^+ ion and Cl^- ion br Why NaCl molecule is easily soluble in water?

In a NaCl molecule there is an attractive force between Na^+ ion and Cl^- ion br Which law help us to find this attractive force? State the law.

An electric dipole placed in an electric field experiences a torque. When a dipole is placed in a uniform electric field the torque acting on it is found to be 0.707 times the maximum torque. Calculate the angle between the Intensity of electric fied and electric dipole moment and draw the orientation of the dipole in the electric field.
