    The AnswerUnderstanding Kirchhoff's Laws and Sign Conventions for RL Circuits

    about kirchoff? Homework Statement can anybody explain why we write kirchhoff laws on RL circuit like -Ldı/dt -iR=0 shouldn't it be written like -Ldı/dt +iR=0 Homework Equations -Ldı/dt -iR=0 -Ldı/dt +iR=0 it is about signs and how we know inductans' poles + or -...

    Why do two point charges with one being zero still exhibit a Coulomb force?

    ı have 5th edition and its may be different because I am not in u.s.a but figure is showed in gauss law

    Why do two point charges with one being zero still exhibit a Coulomb force?

    but ı have seen a figure on serway physics which shows atractive force between neutral and positive charged point charge on page 786

    Why do two point charges with one being zero still exhibit a Coulomb force?

    but why neutral piece of paper and charged plastic rod attract each other

    Why do two point charges with one being zero still exhibit a Coulomb force?

    about coloumb? i wonder why two point charge whose magnitude 0 and +q(or smt different from zero charge) exert a coloumb force to one another .formula says there shoud be no force acting to each other(because of multiplication q1.q2=0) but there is an atraction between them . if this force...
