Potential Energy & Equilibrium: Practice Problem & Solution

A body of mass m is raised to height h from ground along three different paths viz I, II and III against gravity as shown below. If WI, WII and WIII are the work done along the respective paths of I, II and III, then the correct option is (there is no nonconservative force) Potential Energy & Equilibrium diagram: A body of mass m is raised to
WIII > WII > WI
WI > WII > WIII
WII > WI > WIII
WI = WII = WIII

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Potential Energy & Equilibrium. Understanding the underlying formula is key to arriving at the correct answer below:

Work done by conservative force is independent of path taken so, WI = WII = WIII
