Question
Joseph wanted to study the dependence of the gravitational force of attraction between two bodies on the mass of one body. Therefore, he did the required calculations by keeping the mass of the first body and their distance of separation constant and simply varying the mass of the second body. He calculated the value of the gravitational force between those two bodies 10 times by taking different masses for the second body. He then plotted a graph of the calculated data taking the force along the y-axis and the mass of the second body along the x-axis. How would the graph look like?
- It is a straight line parallel to the x-axis
- It is a straight line passing through the origin
- It is a curved line passing through the origin
- It is a curved line that does not pass through the origin
Hint:
It is a straight line passing through the origin.
The correct answer is: It is a straight line passing through the origin

Sherlin wanted to study the dependence of the gravitational force of attraction between two bodies on the distance of separation. Therefore, she did the required calculations by keeping the masses of the two bodies constant and simply varying their distance of separation. She calculated the value of the gravitational force between those two bodies 10 times at different distances of separation. She then plotted a graph of the calculated data taking the force along the y-axis and the distance of separation along the x-axis. How would the graph look like?
