Question

Velocity time graph corresponding to displacement time graph as shown in figure is

• A.
• B.
• C.
• D.

  

Answer 1

The correct option is C

Explanation for correct answer: Option(C)

.

1. From displacement -time graph's slope we can find velocity of particle.
2. In above graph in time interval of $0-t_1$slope will be positive i.e velocity will increase.
3. And after $t_1$, slope will negative, i.e velocity will decrease.
4. So, correct representation will be:

Explanation for Incorrect answer:

Option(A):

1. From displacement -time graph's slope we can find velocity of particle.
2. In above graph in time interval of $0-t_1$slope will be positive i.e velocity will increase.
3. And after $t_1$, slope will negative, i.e velocity will decrease.
4. But, In this graph, velocity is continously increasing.

Option(B):

1. From displacement -time graph's slope we can find velocity of particle.
2. In above graph in time interval of $0-t_1$slope will be positive i.e velocity will increase.
3. And after $t_1$, slope will negative, i.e velocity will decrease.
4. But, In this graph, velocity is continously decreasing.

Option(D):

1. From displacement -time graph's slope we can find velocity of particle.
2. In above graph in time interval of $0-t_1$slope will be positive i.e velocity will increase.
3. And after $t_1$, slope will negative, i.e velocity will decrease.
4. But, In this graph, velocity is increasing and decreasing at random time.
