Practise resolving forces in contact, elevator and accelerating-block problems using free-body diagrams and resultant force.
An elevator (lift) and its load accelerate vertically upwards.
Which statement is correct in this situation?
The net force on the load is zero.
The tension in the cable is equal but opposite to the combined weight of the elevator and its load.
The normal reaction force on the load is equal but opposite to the force on the elevator from the load.
The elevator and its load are in translational equilibrium.
