E=10N
L=9Kg
=9×10=90N
length of crowbar=3
let length of load arm=x
then length of effort arm=3-x
According to the principle of levers
load×load arm =effort×effort arm
90×x =10×(3-x)
90x/10=3-x
9x=3-x
10x=3
x=3/10
=0.3m
load arm=0.3m
effort arm=2.7 m
fulcrum should be placed at distance of 0.3 m from the boulder.
