Work, Power and EnergyHard

Question

Potential energy ( $V$ ) versus distance ( $x$ ) is given by the graph, Rank various regions as per the magnitudes of the force (F) acting on a particle from high to low.

Options

A.$F_{BC} > F_{CD} > F_{DE} > F_{AB}$
B.$F_{CD} > F_{AB} > F_{BC} > F_{DE}$
C.$F_{CD} > F_{DE} > F_{AB} > F_{BC}$
D.$F_{BC} > F_{AB} > F_{DE} > F_{CD}$

Solution

Slope of potential energy $v/s$ position curve gives negative of force.

$$\therefore\ F_{BC} > F_{AB} > F_{DE} > F_{CD}$$
