A metre rule is found to be balanced at 48 cm mark when body of mass 60g is suspended at the 6cm mark , the balance point is found to be at 30cm mark.calculate the metre rule the distance of the balance point from the zero end if the body was to the 13 cm mark
60x(x-13)=80x(48-x)
60x-780=3840-80x
60x+80x=3840+780
140x/140=4620/140
X=33cm
a metres Rule is found to balance at 48cm mark when a Body of mass 60g is suspended at 6cm mark the balance point is found to be at the 30cm mark. calculate in the mass of the metres rule.
U people should show d calculation
It difficult
what's the answer
80g and 18cm
what is the answer pls
No body
Who can answer this pls
A metre rule is found to balance at the 48cm mark when a body of mass 60g is suspended at the 30cm mark calculate the mass of the metre rule and the distance of the balance point from the zero end if the body was moved to the 18cm mark
