Final answer:
The more surface-to-surface contact, the larger the induced dipole will be, due to greater influence on electron distribution between the molecules.
Step-by-step explanation:
The more surface-to-surface contact there is, the larger the induced dipole will be. This is because when two surfaces are in close proximity, the electrons from one molecule can influence the electron distribution in another, creating a temporary dipole moment. In situations where the normal force is larger due to a larger applied force, the area of actual contact increases along with the induced dipole. Additionally, when the curvature of the surface is greater, surface charge density increases at locations with a small radius of curvature. This means that in situations where you have a larger surface area in contact, there will be a greater influence on the charges and therefore a larger induced dipole moment.
