    Two point charges \[I{{\omega }^{2}}\]repel each other by a force of \[I\omega \]. If each of them is given an additional charge \[4\sqrt{3}\], the force between them will be :

    A) \[\frac{T}{\sqrt{3}}\]N(attractive)

    B) \[\frac{T}{3}\] (attractive)

    C) \[\frac{\sqrt{3}}{2}T\] (repulsive)

    D) \[\sqrt{3}T\](attractive)

    Correct Answer: D

    Solution :

    Initial force \[{{10}^{2}}\] \[{{10}^{-2}}\]         ??(i)                                                                             This is repulsive in nature. Force afterwards \[{{10}^{-3}}\] This is attractive in nature. \[{{10}^{-4}}\]      ..?(ii) Now from eqs. (i) and (ii), we get, \[J\]  or  \[\frac{I}{\omega }\] \[I{{\omega }^{2}}\] minus (-) sign indicates that force is attractive
