Two charges  $ + 3.2\, \times \,{10^{ - 19}}\,C$ and $ - 3.2\, \times \,{10^{ - 19}}\,C$ kept $2.4\,\mathop A\limits^o $ apart forms a dipole. If it is kept in uniform electric field of intensity $4\, \times \,{10^{5\,}}\,volt/m$ then what will be its potential energy in stable equilibrium

  • A

    $ + 3 \times {10^{ - 23\,}}\,J$

  • B

    $ -3 \times {10^{ - 23\,}}\,J$

  • C

    $ -6 \times {10^{ - 23\,}}\,J$

  • D

    $ -2 \times {10^{ - 23\,}}\,J$
