Question

The potential energy of a particle varies with distance x as shown in the graph.

The force acting on the particle is zero at

  1. C    
  2. B    
  3. B and C    
  4. A and D    

The correct answer is: B and C


    F equals fraction numerator negative d U over denominator d x end fraction it is clear that slope of U – x curve is zero at point B and C. \ F = 0 for point B and C
