Forces Between Two & Multiple Changes In Air & Other Medium,Intro Nto Electric Field

Force between two points in a medium | Force between multiple charges|Principle of superposition and illustraions on it | Introduction to electric field

Assertion: If the meduim between two charges is replaced by another medium of grater dielectric constant then the electric force between them decreases. Reason: Electric dipole moment varies inversely as the dielectric constant.

The ratio of the force between two small conducting spheres of equal charge in (a) a medium of dielectric constant 2, and (b) air is respectively

Force between two point charges in air at certain distance is 200N. What will force when they are kept in a medium of dielectric constant 4, at the same distance?

Force between two point charges in air at certain distance is 200N . What will force when they are kept in a medium of dielectric constant 4 , at the same distance?

Assertion : Gravitational force between two masses in air is F. If they are immersed in water, force will remain F Reason : Gravitational force does not depend on the medium between the masses.

The force between two point charges in air is 100 N. If the distance between them is increased by 50%, then the force between two charges will be nearly equal to

Statement -1: Gravitational force between two particles is negligibly small compared to the electrical force. Statement-2 :The electrical force is experienced by charged particles only.
