Answer:
Formula for gravitational force F = G M1 * M2 / R^2 where G is the gravitational constant
F2 / F1 = (R1 / R2)^2 = 1/2 where F2 is the required force
R2 = (2)^1/2 R1 distance for R2 to be 1/2 force at R1
Since force is proportional to the square of the distance of separation, increasing the distance of separation by 2^2 will halve the force
