Answer:
how can u put more detail please
The normal force acting on the legs of the table is 175 N
The weight of the books is the force exerted by the books on the table, and it is given as:

The force exerted by the table is given as:

The parameters above imply that:
- The table and the books are stationary,
- The force exerted by both act in the same downward direction.
So, the normal force acting on the legs of the table is calculated as follows:

Substitute known values


Hence, the normal force acting on the legs of the table is 175 N
