Clockwise moments = Anticlockwise moments
Moment=force X distance
Force= (75/1000)X10=0.75N
Force= (125/1000)X10=1.25N
-Let y be the distance between pivot and centre of gravity of the metre rule.
-Distance between the pivot and the supporting spring is 90-20=70cm.
Hence
0.75x70=1.25xy
52.5 = 1.25y
y = 52.5/1.25
y = 42 cm
Position of center of gravity is 20+42 =62
C.o.g = 62 cm mark.
