Velocity-time graph of a moving particle of mass 1 kg is shown below. The force acting on the particle is |
A) 0
B) 4 N
C) 8 N
D) 10 N
Correct Answer: A
Solution :
[a] The slope of velocity-time graph shows acceleration of body. |
Here, velocity is constant. |
So, \[a=\frac{dv}{dt}=0\] |
\[\therefore \] Force F=\[m\times a=1\times 0=0\] |
