A particle moved along the `X-`axis according to the graph shown in Figure. Choose the incorrct options. A. The particle did not move in straight line from `t=0 s` to `t=5s`.B. The magnitude of displacement of particle from `t=0s` to `t=5s` is `2 m`.C. The average speed of particle from `t=0s` to `t=5s` is `0.8 m//s`D. The speed of particle is zero somewhere between `t=3s` to `t=4s`. |

Answer» Correct Answer - A `(1)` since the particle is moving along `x-`axis it is straight line. `(2)` `s=x_(f)-x_(i)=2-0=2m` `(3)` distance `=(3-0)+(3-2)=4` `:.ltVgt.=(4)/(5)=0.8m//s` `(4)` Slope is zero between `t=3` & `4 sec` |
