Gravity Causes Objects To Be Attracted To One Another This Attraction Keeps Our

Gravity causes objects to be attracted to one another. This attraction keeps our feet firmly planted on the ground and causes the moon to orbit the earth. The force of gravitational attraction is represented by the equation,where is the magnitude of the gravitational attraction on either body, and are the masses of the bodies, is the distance between them, and is the gravitational constant. In SI units, the units or force are , the units of mass are , and the units of distance are . For this equation to have consistent units, the units of must be which of the following?
