• # question_answer There uncharged capacitors of capacitance $1\mu f,\,2\mu f$and $3\mu f$ are connected shown in figure. If potentials at point, P,Q and R are IV, 2V, 3V respectively, then, potential at Q is:              A)  $\frac{18}{11}\,V$                   B)  $\frac{11}{18}\,V$C)  $5\,V$                       D)  None of these

From KCL, $1(V-1)+2(V-2)+3(V-3)=0$ (Here V= Potential point m)             $V=\frac{7}{3}$ Volt             (Note that the net change on the plates connected to the M is zero.)
