Question

An elevator is being lifted at a constant Motor speed by a steel cable attached to an electric motor. Which statement is corr

please explain, thanks

Answer 1

Answer #1

The cable exert an upward force on the elevator and elevator's displacement is also in upward direction, so cable does positive work on elevator.

The elevator exerts a downward displacement on the cable which moves upward, so work done is negative.

Option b is correct
