A forceacts between sodium and chloride ions of salt when put 1 cm apart in air The permittivity of air and dielectricconstant of water are E and K respectively when a piece of salt is put in water electrical force acting between sodium and chlorine ions 1 cm apart is

Dear pallavi

when ions are placed in air

F_a= (1/4∏E) qq /(.01)²

when ions are placed in the water

F_w = (1/4∏EK) qq /(.01)²

      =F_a/K
