Which relationship best describes how the magnitude of the electrostatic force between two isolated point charges depends on the separation distance

r

between them? (a) It is inversely proportional to the distance

r

. (i.e.,

F\propto 1/r

) (b) It is inversely proportional to the square of the distance

r

. (i.e.,

F\propto 1/r^{2}

) (c) It is directly proportional to the square of the distance

r

. (i.e.,

F\propto r^{2}

) (d) It is inversely proportional to the cube of the distance

r

. (i.e.,

F\propto 1/r^{3}

)
