										Its well known concept that outside the conducting charged body, finding the electric field, the body behaves as point charge,
Here, we are given that charge is spreaded over the ramp surface only,
so electric flux due to ramp part + Flux due to base area = 0
So, flux due to ramp part = – flux due to base area
Now consider the base area as disc, and find the electric field and calculate the work done in bringing the charge ‘q’ from infinite to centre....

Good Luck.....................................................
