The force of attraction, $$\(F\)$$ Newtons, between two magnets is inversely proportional to the square of the distance, $$\(d \mathrm{~cm}\)$$, between the magnets. When $$\(d=1.5, F=48\)$$. Find an expression for $$\(F\)$$ in terms of $$\(d\)$$. $$\[ F=............................................. \]$$
