Question

Two very small spheres having charge +Q, and -Q face each other at a certain distance between them. If a dielectric having dielectric constant K inserted between them then electrostatic force between them

Increase

Decrease

Remains same

Becomes zero​

Answer 1

Answer:

b

Explanation:

Now, in initial conditions, the electrostatic force in between the charges will be :

But now, a dielectric material of DIELECTRIC CONSTANT 'K' is placed in between the charges.

So, new electrostatic force is:

Now, comparing the Equations:

Since value of K > 1 , depending on the medium.

So, force decreases.
