A person of mass 60 kg stands on a weighing scale in a lift (elevator). What would the scale read if the elevator moves (i) up with a uniform speed of 5 m//s (ii) down with a uniform acceleration of 4 m//s^2 (iii) up with a uniform acceleration of 4 m//s^2 ? [Given : g = 10 m//s^2 ]

A simple pendulum of length 1 m is freely suspended from the ceiling of an elevator. The time period of small oscillations as the elevator moves up with an acceleration of 2m//s^2 is (use g=10 m//s^2 )
