Question

In the scenario described by the equation 13–98, a 2-lb spool slides along a smooth horizontal spiral rod. What is the net force acting on the spool?

Options:
a) 0 N
b) 2 N
c) 9.8 N
d) 13 N

Answer 1

Since the spool is on a smooth horizontal surface and no other forces are mentioned, the gravitational force and normal force would cancel each other out, resulting in a net force of 0 N.

Step-by-step explanation:

The question pertains to the concept of net force in physics. The scenario involves a 2-lb spool sliding along a smooth horizontal spiral rod. The equation mentioned, 13–98, seems to be a typo and is not relevant to calculating the net force in this context. Under ideal conditions with no friction (a smooth surface as mentioned), only external forces like gravity, normal force, or applied forces can affect the spool. However, since the spool is on a horizontal surface, the normal force and gravitational force would cancel each other out, leading to a net force of 0 N if no other forces are applied. Therefore, the answer would be 0 N.
