As we learned

Constant Proportionality (k) -

In S.I

K=\frac{1}{4\pi \varepsilon _{0}}

In C.G.S

K=0

 

 

- wherein

\frac{1}{4\pi \varepsilon _{0}}=9\times 10^{9}    \frac{Nm^{2}}{c^{2}}

 

 \varepsilon =K\varepsilon _{0}=81\times 8.854\times 10^{-12}=7.12\times 10^{-10}MKS\; units

 


Option 1)

7.12\times 10^{-10}\:MKS\; \; units

Option 2)

8.86\times 10^{-12}\:MKS\; \; units

Option 3)

1.02\times 10^{13}\:MKS\; \; units

Option 4)

Cannot be calculated
