An infinite number of charges, each equal to 'Q'  coulomb, are placed along the x-axis at x(inmeter)=1,2,4,8....  and so on.  The potential in SI units at x=0  due to this set of charges are respectively 14π0   times.

a
2Q3
b

d
4Q

detailed solution

Correct option is B

electric potential is V= 14πεoqr here sum of all potentials is V= V1+V2+ ............ V= 14πεo11+ 12 + 14+ 18+.........V= 14πεo11-12  (sum of infinte GP)V=2Q14πεo
