A force of 4N is acting between two charges in air.If the space between them is completelly filled with glass (epsilon_(r)=8) then the new force will be

The force of attraction between two charges separated by certain distance in air is F_(1) .If the space between the charges is completely filled with dielectric of constant 4 the force becomes F_(2) .If half of the distance between the charges is filled with same dielectric the force between the charges is F_(3) Then F_(1):F_(2):F_(3) is

The force between two point charges in air is 100 N. If the distance between them is increased by 50%, then the force between two charges will be nearly equal to
