if two objects each with a mass of 3.7x10^3 N produce a gravitational force between them of 4.8x10^-6 N. what is the distance between them?

f = G * M1 * M2 / d^2

the masses are listed in Newtons, a force unit
... maybe a typo?

the gravitational force equation uses mass
... is this happening on Earth? ... is g need for conversion?
