MCQ
Which one of the following represents the displacement time graph of two objects $A$ and $B$ moving with zero relative speed?
- A
- ✓
- C
- D
✓
Answer
Correct option: B.
If relative speed $= 0$ then velocity of $A =$ velocity of $B.$
So displacement time graphs of $A$ and $B$ must have same slope $($other than zero$).$
So displacement time graphs of $A$ and $B$ must have same slope $($other than zero$).$
