Answer:
r/2>r>2r>4r
Explanation:
if radius is half then the gravity will be double and single is r then gravity will be 9.8 m/s^2. if radius is 2r then the gravity will decrease and if radius is 4r then the gravity will also decrease because the gravity is inversely proportional to the square of radius.
