How does the electric force between two charged objects change?

1 Answer

Inverse square variation, #F\prop\frac{1}{D^2}#

Explanation:

Electrostatic force between two point charges #Q_1# & #Q_2# separated by a distance #D# is given as folows

#F=\frac{1}{4\pi \epsilon_0}\frac{Q_1Q_2}{D^2}#

#F\prop\frac{1}{D^2}#

hence the electrostatic force between two point is inversely proportional to the square of distance between the charges
