Topic: Work Energy and Power

Subtopic: Potential Energy & Equilibrium

Potential energy of a particle at position x is given by U = x² – 5x. Which of the following is equilibrium position of the particle?

x = 0

x = 2.5 m

x = 5 m

x = 7.5 m

For Equilibrium,

dU/dx = 0

⇒ d(x²-5x)/dx=0

⇒ 2x-5 = 0

⇒ x =2.5 m
