G=50.0cm
Y=30.0cm

Slope =βM/βX^-1= M2-M1/(X^-1) – (X^-1)
S= 120.0 -40/80.0-27
S= 80/53
S=1.509*10^3
S=1509

(x)
S=ymo
1509=30mo
mo=1509/30
mo=50.3

(1xi)
(ii)Avoid error due to parallax
(1bii)
CWM = ACWM
60*25 = x *30
30x = 1500
Divide through by 30
30x/30 = 1500/30
x=50g

The mass that should be placed at the 80cm mark of the meter rule to balance it horizontally is 50g

(1bi)
Moment of a force can be defined as the product of the force and its perpendicular distance from its point of action.
