Answer #1

The charge per unit length on the given segment of y-axis is

The charge on the elemetal length 'dy' is

The electric field due to this elemental length at x= 2 m is

So, the electric field at x=2 due to the whole segment is

Where k= 9 X 109 Nm​​​​​2/C​​​​​​2 is proportionality constant.
