Question

Motion of bodies A and B is depicted by the x-t graph. Now consider the following statements (a), (b), (c) and (d) and select the incorrect option.
(a) A has uniform motion
(b) B has less velocity than A initially
(e) B crosses A at a displacement X
(d) A comes to rest at a displacement X

• A. Only (a)
• B. (b) and (c)
• C. (b),(c) and (d)
• D. All of them

Answer 1

The correct option is A Only (a)

Answer is A.
According to the graph given, the body A does not have uniform motion. An object is said to be in uniform motion when it covers equal distances in equal intervals of time. In this case, it accelerates to a particular velocity and remains the same continuously. Otherwise, it is evident that the velocity of B is lesser that A initially and the body B crosses A at X.
Hence, the statement A has uniform motion is not correct.
