Passage / Comprehension
In a certain building, a lift moves with a constant magnitude of acceleration. The v-t graph (upward velocity being taken positive) shows the lift's motion between the ground floor and the first floor. The lift starts at t = 0 from ground floor and comes back to the ground again after reaching upto the first floor.
A spring balance is attached to the ceiling of the lift. Plot a graph for the reading of the spring balance (in Newtons) with respect to time if a 2 kg mass is hung from it ( ) Ignore any fluctuation in reading during change in acceleration of lift.
