The magnitude of non-contact force depends upon:
The distance of separation between two bodies affects the magnitude of the non-contact force between them such that
The interaction energy of London force is inversely proportional to sixth power of the distance between two interacting particles but their magnitude depends upon
(a) charge of interacting particles
(b) mass of interacting particles
(c) polarisability of interacting particles
(d) strength of permanent dipoles in the particles
"The magnitude of non-contact forces depend upon distance between two bodies". The given statement is
Which of the following is/are true about frictional force?
1. It depends on the nature of the surface in contact.
2. It always opposes relative motion between two objects.
3. It is a contact force.
4. It is a non- contact force.
The force of attraction or repulsion between two charged bodies depends on the distance between them.
