Is there a formula to find the force of attraction between a charged and an uncharged body.If yes how it is derived. If no , why haven't anyone thought about it till now?

There is no separate formula to find the force of attraction between a charged and uncharge body same force formula you can use that you use for force between two charged body.In the case of charge and uncharged body we have to calculate induced charge value separately that value we can calculate using maxwell's equation,after getting induced charge value we can use general formula of force between two charge body for calculating the force.
Here is the explanation why charge and uncharge body attract each other This is due to the phenomenon of "Charging by Induction". When a charged body(say negatively charged) is brought near an uncharged one, it induces an opposite charge(positive) on it and hence attracts it towards itself. This can be explained as follows :-
The negatively charged body can be thought to be an electron rich specie. When brought near the uncharged body, it repels the free electrons from the uncharged body towards its farther end. As such, the closer end of the uncharged body now experiences lack of electrons, which is a characteristic of positive charge. Hence, the ends of the two bodies develop opposite charges and mutual attraction occurs.
The same theory applies for a positively charged body which can attract an uncharged one.
