Question Number 21516 by Tinkutara last updated on 26/Sep/17

A 5 - kg body is suspended from a spring -

balance, and an identical body is

balanced on a pan of a physical

balance . If both the balances are kept

in an elevator, then what would happen

in each case when the elevator is moving

with an upward acceleration ?

ajfour Sir, can you see Q . 21307 ?

In first case, the reading of spring balance increases but in

second, there will be no effect on physical balance because

on both sides of physical balance, there are equal masses .
