The equilibrium condition allows finding the result for the force that the chair exerts on the student is:
Newton's second law gives the relationship between force, mass and acceleration of bodies, in the special case that the acceleration is is zero equilibrium condition.
∑ F = 0
Where F is the external force.
The free body diagram is a diagram of the forces on bodies without the details of the shape of the body, in the attached we can see a diagram of the forces.
Let's analyze the force on the chair.
[tex]N_{chair} - W_{chair} - W_{student} = 0 \\ \\N_{chair} = W_{chair} + W_{student}[/tex]
Let's analyze the forces on the student.
[tex]N_{student} - W_{student} = 0 \\N_{student} = W _{student}[/tex]
In conclusion using the equilibrium condition we can find the result for the force that the chair exerts on the student is:
