The given plot shows the variation of U, the potential energy of interaction between two particles with the distance separating them is r. Then which of the following statements is / are correct.:
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b, d) At point 'C', the potential energy is minimum, hence it is a point of stable equilibrium.
Also, from E to F, the slope is negative i.e.,
F = – 
F is +ve so repulsive
Hence, the force of interaction between the particles is repulsive between points E and F.
