The figure below shows the force diagram for an elevator moving upwards. The system we are considering energies for includes only the elevator. Fcable on Elevator FEarth on Elevator Choose the correct statement: O The cable does positive work, increasing the total energy of the system The cable does negative work while the Earth does a smaller amount of positive work, decreasing the total energy of the system O The cable does negative work, decreasing the total energy of the system The energy of the system cannot change since energy is a conserved quantity O The cable does positive work while the Earth does a smaller amount of negative work, increasing the total energy of the system
