The forces exerted upon surface areas

[lpbug]

For example, I have a floating disk,and there are four propulsors, the propulsors of this disk could generate unlimited opposing force (to the gravity). Let's say this disk weighs 100 grams and I want to find out the gravitational pull on this object and the opposing force required, how do I do it?(No crazy-math explanation please! =))

You can solve it, but first you must resort to using crazy math.
