I have this problem which I don't understand from where they got the solution I tried to solve it with slot of methods with the same answer which not the stated answer.

A point charge (q) is located a distance (b) from a grounded conducting sphere with radius (a) show that the ratio between the induced charge of the part in the front of (q) to the rest part is

√(a+b)/√(b-a)

I tried a lot of but each time I got the following answer

√(b

^{2}- a

^{2}+2ab)/√(b

^{2}- a

^{2}- 2ab)
