Question

If the elevator is moving upwards with constant acceleration 1ms 2 , the
tension in the string connected to block A of mass 5 kg would be (take g = 10 m/s2)
A
a=1ms -2
(A) 30 N (B) 55 N
(C) 20 N (D) 85 N

Answer 1

g = 10 m/s²(downward)
a = 1 m/s² (upward)
g' = g-a = 10+1 = 11 m/s²
mass = 5 kg
Tension = mg' = 5×11 = 55N
