Question 1 of 5

The force for 1m length between two currents can be derived by using Ampere’s law. Magnetic Coulomb’s law constant is given by $k_{m}$ . If the constant of Coulomb’s law, derived by Gauss law, is $k_{c}$ then which of the following is the ratio of $k_{m} / k_{c}$ ?

A

$4 \varepsilon_{o} \mu_{o}$

B

$\varepsilon_{o} \mu_{o}$

C

$\varepsilon_{o} \mu_{o} / 2$

D

$2 \varepsilon_{o} \mu_{o}$
