A uniform ladder of mass 10 g leans against a smooth vertical wall making an angle of `53^0` with it. The other end rests on a rough horizontal floor. Find the normal force and the frictional force that the floor exerts on the ladder

Text Solution

Verified by Experts

`N_(1)=10g=100N`

Balancing torque about `A`
`10gl/2cos37^@=N_(2)lcos53^@`
`N_(2)=(2omega)/3N`
Now `f_(1)N_(2)=200/3N`
