• What is the gravitational force acting on the weight? Explain.

• What is the net force acting on the weight? Explain.

Respuesta :

Answer:

a) W = -4N,   b)  F_net = 0

Explanation:

The suspended weight of the spring ladder is subjected to two forces: the elastic force of the spring directed downwards and the gravitational force directed downwards.

             [tex]F_{e}[/tex] - W = 0

             F_{e} = W

             F_{e} = W = 4 N

a) the gravitational force is the weight of the body

             W = -4N

b) as the system is in equilibrium, the net force is zero

             F_net = 0
