"static" equilibrium means that the object remains at rest
... the forces must cancel each other , and be applied simultaneously
B looks good
Study the scenario.
An object is at rest. At five seconds, someone comes over and pushes the object with a force of 3 N to the right.
Which of the following choices describes the force needed to keep the object in static equilibrium?
a. A force of 3 N to the left must be exerted on the box at any time after 5 seconds so that the forces are balanced and the object moves at constant velocity.
b. A force of 3 N to the left must be exerted on the box at exactly 5 seconds, so that the forces are balanced and the object remains at rest.
c. There is no way to keep the object in static equilibrium once the person exerts the 3 N force on the box.
d. A force greater than 3 N to the left must be exerted on the object at exactly 5 seconds to prevent the object from moving.
I Know 100% that it isn't A and I don't think it is C so do you think it could be B?
