a) A seesaw consisting of a uniform board of mass M and length l supports a father and daughter with masses me and ma respectively, as shown in the Figure below. The support is under the center of gravity of the board, the father is a distance d from the center, and the daughter is a distance - from the center. 21 €/2 Mg Determine the magnitude of the upward force n exerted by the support on the board Determine where the father should sit to balance the system

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.
