Question 19 of 210

The figure represents the momentum time $(p-t)$ curve for a particle moving along an axis under the influence of the force. Identify the regions on the graph where the magnitude of the force is maximum and minimum respectively ?

Answer: (C) c and b

From Newton's second,
$\left|F\right|=\left|\dfrac{dp}{dt}\right|=\left|slopeofp-tcurve\right|$
From the given graph, we can see that slope of region $c$ is maximum and slope of region $b$ is minimum.
Thus, $\left|{F}_{c}\right|\gt \left|{F}_{a}\right|\gt \left|{F}_{b}\right|$.
