Electric Charges And Fields

An infinite no.of electric charges each equal to 5 nano coulombs are placed along X-axis at x = 1 cm, x = 2cm, x = 4cm, x=8cm,…. and so on. In this setup, if the consecutive charges have opposite sign, then the electric field in newton/coulomb at x = 0 is

1) 12 × 10⁴
2) 24 × 10⁴
3) 36 × 10⁴
4) 48 × 10⁴
