Expert Solution

Step 1
According to Coulomb's law the electric field at a point (x,y) due to a charge q at (x',y') is given by,
Consider the situation as below,
Let the linear charge density of the charge on the rod be,
Then the electric field at (x,y)=(0,d) due to a differential length element dx of the charged rod positioned at (x',y')=(x',0) having charge , using (1) is,
