You tie a string to a rock weighing 50 lbs and lower it beneath the surface of the water. When the rock is completely submerged, you find (know) that you have to support a weight less than 50 lbs. As the boulder is lowered deeper (submerged further), the force needed to support the boulder increase, decrease or remain the same?
