Question

A student places a set of books with a force of 25 n on a lab table with a force of 150 n. What is the normal force pushing upward on the legs of the table?.

Answer 1

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:

$W =25N$

The force exerted by the table is given as:

$F = 150N$

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:

$F_N =F +W$

Substitute known values

$F_N = 150N + 25N$

$F_N = 175N$

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