r=((112452−(((2108)(3820))/(80)))/( (√(67778−(((2108)^2 )/(80))(√(232470−(((3820)^2 )/(80))))))))

$r = \frac{112452 - \frac{(2108) (3820)}{80}}{\sqrt{67778 - \frac{{(2108)}^{2}}{80} \sqrt{232470 - \frac{{(3820)}^{2}}{80}}}}$

A uniform stick AB of length L and mass M is balanced horizontally on a knife edge 10.0cm from A when an object of mass 400g is suspended at A. When the knife edge is moved 5cm further, the object has to be moved to a point 9.00cm from A for the stick to balance. Represent the balance system with a suitable diagram, determine the mass and Length of the stick
