Question

The given plot shows the variation of U, the potential energy of interaction between two particles, with the distance separating them, $$r(i)$$ B and D are equilibrium points. (ii) C is a point of stable equilibrium. (iii) The force of interaction between the two particles is attractive between points C and B, and repulsive between points D and E on the curve. (iv) The force of interaction between the particles is repulsive between points C and A. Which of the above statements are correct?

Infinity Learn · Accepted Answer

At point C the potential energy is minimum. Hence, it is a point of stable equilibrium. Also, from C to A, the slope is negative, i.e., dUdr<$$0Hence$$, the force of interaction between the particles is repulsive between points C and A.
