Potential Energy — GraphMediumQuestion 30429

Question

At a point where the PE curve has zero slope (dU/dx = 0), the force on the particle is:
  1. A
    Maximum
  2. B
    Minimum
  3. C
    Zero
    Correct
  4. D
    Equal to −U

Correct answer

Zero

Explanation

F = −dU/dx. Where the slope of the PE curve is zero, the force is zero — this corresponds to a point of equilibrium.
