Abrick is lying on a table in a state of static equilibrium. if the mass of the brick is 7.52 kilograms, what is the normal force exerted by the table on the brick?
a. −73.7 newtons
b. 73.7 newtons
c. 80.7 newtons
d. 7.52 newtons
e. 8.07 newtons
i believe the answer is either a. or b.—i'm just not sure if it should be expressed as a negative or not because the force is acting in the opposite direction.
