\(B\) નું સ્થિતિમાન \({V_B}\,\, = \,\,\frac{{K\,\, \times \,\,1{0^{ - 3}}\,\, \times \,\,{{10}^{ - 6}}}}{{\,2}}\)
સ્થિતિમાન તફાવત \(\left( {{V_A}\,\, - \,\,{V_B}} \right)\,\, = \,\,0\therefore \,\,\overrightarrow r \,\, = \,\,\sqrt 2 \,\hat i\,\, + \;\,\sqrt 2 \,\hat j\,\,\therefore \,\,|\overrightarrow r |\,\, = \,\,2\)
