Question

Select One Option Correct from the following A charge +q is fixed at each of the points $x = x_0, x=3 x_0, x= 5x_0....., \infty$ on the x-axis and a charge -q is fixed at each of the points $Q/4 \pi \epsilon r$ , Then, the potential at the origin due to the above system of charges is
(A) zero
(B) $\frac{q}{8 \pi \epsilon_0 x_0 \ln 2}$
(C) infinite
(D) $\frac{q \ln 2}{4 \pi \epsilon_0 x_0 }$

Answer 1

(B) $\frac{q}{8 \pu \epsilon_0 x_0\In 2}$
