Question

what is the value of 1/4πE0?

Answer 1

9×(10^9) aaaaaaaaaaaaaaaaaaaa

Answer 2

The value of $\dfrac{1}{4\pi \epsilon_o}$ is $9\times 10^9\ Nm^2/C^2$.

Explanation:

In this case, it is required to find the value of $\dfrac{1}{4\pi \epsilon_o}$. It is known as electrostatic constant. $\epsilon_o$ is known as relative permittivity of the vacuum. It is equal to $\epsilon_o=8.85\times 10^{-12}\ F/m$.

Its value can be calculated as :

$\dfrac{1}{4\pi\epsilon_o}=\dfrac{1}{4\pi8.85\times 10^{-12}}$

$\dfrac{1}{4\pi\epsilon_o}=8.991\times 10^9\ Nm^2/C^2$

$\dfrac{1}{4\pi\epsilon_o}=9\times 10^9\ Nm^2/C^2$

So, the value of $\dfrac{1}{4\pi \epsilon_o}$ is $9\times 10^9\ Nm^2/C^2$. Hence, this is the required solution.
