Q 3.2 The position-time (x-t) graphs for two children A and B returning from their school O to their homes P and Q respectively are shown in figure. Choose the correct entries in the brackets below
(b) (A/B) starts from the school earlier than (B/A)
From the graph, we can see that the position of A starts changing at time t=0 whereas in case of B starts changing at some finite time and therefore A starts from the school earlier than B.
