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
