[Q80BOY]

11.1CM FROM THEcentre.

how ?? the whole diagram is 9 cm only 

[hyebyekadal]

qboy he said from centre and no the whole thing is not 9cm its 100cm checkq and any the ms say the ottherway around why?

mass on correct side [1]
approx twice as far from pivot (by eye) [1]
(between 35 and 40)

[astarmathsandphysics]

55.5*20=100*x so x= 1110/100=11.1 and this is the correct answer.

[hyebyekadal]

so ms  is wrong?

[Q80BOY]

55.5*20=100*x so x= 1110/100=11.1 and this is the correct answer.

[hyebyekadal]

MY QUESTION  is why does the ms say otherwise? AHHH TO MUCH TO STDY!!

[astarmathsandphysics]

Does the ms say from the edge or the centre? I say from the centre.

[Q80BOY]

Does the ms say from the edge or the centre? I say from the centre.

it says

mass in correct side [1]
approx twice as far from pivot (bye eye) [1]
          (between 35 and 40)

[astarmathsandphysics]

In that case I think the ms is wrong.
