The force, F (Newtons), between two objects is inversely proportional to the square of

The force,
F (Newtons), between two objects is inversely proportional to the square of the distance, d (metres), between them.The force is 0.045 Newtons when the distance between the objects is 2.4 metres.Work out d (rounded to 2 DP) when F=0.7 Newtons.
