Shown in the figure is the position-time graph for two chldren `(C_1` & `C_2)` going home from the school. Which of the following statements(s) about their relative motion is/are true after both of them started moving? Their relative velocity: (consider 1-D motion)

A

first increases and then decreases

B

first decreases and then increases

C

is zero

D

is non zero constant

Text Solution

Verified by Experts

The correct Answer is:
D
`upsilon_(1)`=slope of `C_(1)` line =constant
`upsilon_(2)`=slope of `C_(2)` line =constant
`upsilon_(1)-upsilon_(2) ne0` but constant
