A uniform stick can be balanced on a knife edge 10cm from one end when a load of 200N is hung from that end. When the knife edge is moved 5cm further from the end, the 200N load has to be moved to a point 8.75cm from the knife edge to obtain a balance. Find the length of the stick and its weight.

Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
