An infinite number of electric charges each equal to 5 nC (magnitude) are placed along \( x \)-axis at \( x=1 \mathrm{~cm} \). \( x=2 \mathrm{~cm}, x=4 \mathrm{~cm}, x=8 \mathrm{~m} \ldots \ldots \ldots \) and \( y 0 \) on. In the setup, if the consecutive charges have opposite sign, then the electric field in newton/coulomb at \( x=0 \) is \( \left(\frac{1}{4 \pi E_{0}}=9 \times 10^{9} \mathrm{~N}-\mathrm{m}^{2} / \mathrm{C}^{2}\right) \)
(A) \( 12 \times 10^{4} \)
(B) \( 24 \times 10^{4} \)
(C) \( 36 \times 10^{4} \)
(D) \( 48 \times 10^{4} \)
