Question

An elevator is ascending at a constant velocity. A block of mass m is suspended from the ceiling of the elevator by a rope, as shown in the figure 1) Which of the following is true of the magnitude of the tension T in the rope? O T mg (but greater than zero) Now assume the elevator is accelerating upward with a constant non-zero acceleration. 2) Which of the following is true of the magnitude of the tension T in the rope? OT-mg O T <mg (but greater than zero) T=0 Now assume the elevator is accelerating down with a constant non-zero acceleratior 3) Which of the following is true of the magnitude of the tension T in the rope T<mg (but greater than zero) T mg 0 Type here to search Ie

Answer 1

A) T = m g

B) T = m(a + g) => T > m g

C) T = m(g - a) => T < m g

D) T = m(g - g) => T = 0
