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 . Choose the correct entries in the brackets
.
a.` (A//B)` Iives closer to school than `(B//A)`.
b. `(A//B)` starts from the school earlier than `(B//A)`.
c. `(A//B)` walks faster than `(B//A)`.
d. `A` and `B` reach home at the (same//differnt) time.
e. (A//B) overtakes on the road (once//twice).

Text Solution

Verified by Experts

a. It is clear from the graph that `OP lt OQ`. A loves closer to the school than `B`.
b. As starts from `t=0` will `B` sstarts little later. So `A` starts from the school earlier than `B`.
c. The slope of `x-t` for motion of `B` g t slpoe of `x-t` A. therce `B` walks fasster than `A` .
d. The value of `t` corresponding to positions `P` and `Q` of the there homes is samd, So `A` and `B` reach home at the same time.
e. It is clear form the gragh `B` overtakes `A` once on the road.
