Q. Two charged sphere A and B, shown below are isolated conductors, A having +Q charge and $B$ having $+ 4 Q$ charge and radius $r_{A} = 1/2 r_{B}$ . OX, is a straight line passing through their centres.

The potential ‘ $V$ ’ at any point on $OX$ , plotted against the distance ‘ $x$ ’ of the point from $O$ , will be nearly
