Question

why the force between two charges placed in water is less than in air at same distance apart explain​

Answer 1

Answer:

The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrup

What is the force between two charged objects when the space between them is partially filled by a dielectric medium?

homework-and-exercises electrostatics dielectric

I am given two charged particles of same charge at a distance of rr. They initially apply force FF.

Now an infinite dielectric (of dielectric constant 44) of width r2r2 is introduced between the particles. What will be the new force?

I find this problem confusing because I have only been told about forces when its either fully dielectric or fully vaccum given by Coulomb's law. How do we get forces when only partial space is dielectric?

I note the close votes, but I hope my answer explains the concepts involved without just doing Sigma's homework. This seems to me to be in the spirit of the Physics SE. – John Rennie Nov 5 '14 at 16:59
