While you push a box you begin to decrease the force you are exerting on the box. When will the box reach static equilibrium?(1 point)
Responses

When Fpush=Ffriction
When cap f sub p u s h is equal to cap f sub f r i c t i o n

When Fpush>Ffriction
When cap f sub p u s h is greater than cap f sub f r i c t i o n

When Fpush<Ffriction
When Fpush<Ffriction

The box will not reach static equilibrium.

Answer 1

The box will reach static equilibrium when the force you are pushing with (F_push) equals the force of friction (F_friction). Therefore, the correct response is:

When Fpush=Ffriction (or equivalently, When cap f sub p u s h is equal to cap f sub f r i c t i o n).
