Question
Calculate the force of gravitation due to earth on a man weighing 100 kg standing on the ground? (Mass of earth 
, Radius of the earth 
)
- 977 N
- 1000 N
- 1230 N
- 1524 N
Hint:
Use the formula of gravitational force.
The correct answer is: 977 N
The correct option is a)977 N.
Given, m= 100Kg
Mass of earth = 6 x 1024
Gravitational constant= 6.67 x 10-11
We will use the formula,
F = 977 N

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?
