coulomb's law

suppose, the electric force between two charged particles were independent of distance.in this case would a neutral insulator still be attracted towards comb??????????????

who ever replies solid reasons are a must.

mind is empty now.. pls tell me wat is "comb"..

No it would not be

that is because the charges are seperated when the get attracted...

so that separation causes the difference in pull due to the comb...

but if the pull were independent of the distance, there would be no net force.. hence not attracted..

comb bole to wo jo hanth me le kar koi mirror ke samne khud ko niharta rehta hai.

actually i didn get dis line "in this case would a neutral insulator still be attracted towards comb?????????????? "

sir,
i could not get it.in question it is given that force is independent of distance.

so,i think whatever be distance between the charges the force will be always same.(only dependent on charges).so, howcum net force would be zero.

plz explain...i think i could not understand completely.

nishant sir......please suggest something.

2johncena actually force b/w comb n neutral insulator is due to the dependence on r suppose the comb is positive charged then in neutrl insulater arrangement ll b done in such a way that negative charge is at near end n positive at far end .this is due to distance dependent nature na . if e field is not r dep so no arrangement n thus no attraction .i hope u understood[1]

oh,i seem to be totally confuse.can the things be made still more simpler.

john

give this answer you will get the full answer.. why is there force when we bring a charged comb near a metallic sphere?

see this.. the foce due to the blue line will be equal to the golden line

they will be equal... and cancel each other out!
