SI unit of permittivity ( ϵ ) is….. (if Coulomb (C), Meter (m) and Force (N) are fundamental Quantities Options: A . &nbspC2m−3N−1 B . &nbspC−1m2N−2 C . &nbspC2m2N2 D . &nbspC2m−2N−1

Answer: Option D : D F= 1 4 π ϵ q 1 q 2 r 2 ⇒ ϵ = 1 4 π q 1 q 2 F r 2 = C 2 m − 2 N − 1

SI unit of permittivity (ϵ) is….. (if Coulomb (C), Meter (m)

Question

SI unit of permittivity

(ϵ)

is….. (if Coulomb (C), Meter (m) and Force (N) are fundamental Quantities

Options:

A . C2m−3N−1

B . C−1m2N−2

C . C2m2N2

D . C2m−2N−1

Answer: Option D
:
D
F=

\frac{1}{4 π ϵ} \frac{q_{1} q_{2}}{r^{2}} \Rightarrow ϵ = \frac{1}{4 π} \frac{q_{1} q_{2}}{F r^{2}} = C^{2} m^{- 2} N^{- 1}
