Scientists are trying to determine the effect of mass on the force of gravity between two objects. In this experiment, then scientists use the following procedure: 1) Place two large, empty barrels exactly 1m apart. 2) Measure the gravitational force between the two barrels and record in data table. 3) Add 10kg of water to each barrel. 4) Measure the gravitational force between the two barrels and record in data table. 5) Repeat steps 3 & 4 until the barrels are completely full of water. 6) Create a graph of Gravitational Force vs Mass from the data collected. What should the graph from Step 6 look like? A) A B) B C) C Eliminate D) D
