Question

write s.i unit of electricfield intensity and write s.i unit of electric dipole moment

Answer 1

s.i. unit 
electricfield intensity = newtons/coulomb   or   volts/meter
electric dipole moment = Coulomb-meter.  

Answer 2

s.i unit of electric field intensity => newton per meter (NM-1)

s.i unit of electric dipole movement => coulomb/meter
