Question

The figure shows momentum versus time graph for a particle moving along x-axis. In which region force on the particle is large. Why? ​

Answer 1

Answer:

Net force is given by $F_{ net }$ = dp / dt

Also, rate of change of momentum = slope of graph.

As from graph,$slope_{ AB }$ = $slope_{CD}$

And slope (BC)= slope (DE)=0 W

So, force acting on the particle is equal in regions AB and CD and in regions BC and DE (which is zero).
