Question Description:

this is a two part question. I am putting both questions but I answered the first question. the data is needed to answer the second question so I thought I include both. here it goes. Balance the meter ruler at the 60 cm mark by suspending 100 g from a suitable point C. Measure the distance of C from the 60 cm mark and record it as x. Suspend a mass M = 20 g from G, the center of gravity and balance the ruler again by moving the 100 g mass to a suitable point. Measure and record x again. Repeat the experiment by suspending 40, 60, 80, 100, 120, 140, 160, 180 and 200 g from G and measure the value of x each time. Tabulate neatly the values of M and x showing the unit of measurement appropriately. here is the table that I made. M(mass) X(cm) 20 13 40 15.5 60 17.5 80 19 100 21.5 120 23.5 140 25.5 160 28 180 30 200 32.5 here is the question i need help with Draw a diagram showing all the forces acting on the meter ruler when a mass M is hung from its center of gravity and the ruler is balanced at the 60 cm mark with the 100 g mass hung from the point C. Taking the weight of the ruler as W and keeping all the units in N and m, take the torque of all forces about the 60 cm mark and write down an equation connecting M, x and W. Arrange this equation in the form y = mx + b and identify m and b in your equation.
