## What is the value of electrostatic force constant?

The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI units it is equal to 8.9875517923(14)×109 kg⋅m3⋅s−2⋅C−2.

## What is the value of k in free space?

9 × 109The value of K in free space is 9 × 109.

## What is the value of k for vacuum?

k is a constant of proportionality known as the Coulomb constant, having the value 9 x 109 N.m2 / C2 in a vacuum.

## What are the units for K in physics?

k is a constant called the rate or spring constant (in SI units: N/m or kg/s2).

## How do you calculate electrostatic force?

Calculate the electrostatic force using the formula: F = K[q1 x q2]/D^2 where K is coulombs constant, which is equal to 9 x 10^9 Nm^2/C^2. The unit for K is newtons square meters per square coulombs.

## What does Coulomb’s law state?

Coulomb’s law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.
