If the gravitational force between two masses located a distance 100 m apart is f, what would be the force between these objects if the distance between them increases to 800 m?

Explanation:

m = product of masses of two objects

r = distance between the two objects = 100 m

F = initial force between the two object

r' = new distance between the two objects = 800 m

F' = new force between the two objects = ?

k = constant of proportionality

initial force between the two object is given as

                                    eq-1

new force between the two objects is given as

                                 eq-2

Dividing eq-2 by eq-1

Inserting the values

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq

v 154.9= 0.9 length length s little over 154.9cm
