MHT CET 2023 Physics question
The potential energy of a molecule on the surface of a liquid compared to the molecules inside the liquid is
Answer: (D)
Solution
A molecule inside the liquid is attracted equally in all directions by its neighbours (within the range of molecular attraction), so the net force is zero and it has the lowest potential energy. A molecule at the surface has neighbours only on one side (below), so there is a net inward pull; to bring a molecule from
