Question

2. Define one coulomb charge. Two point charges at a distance r in air exert a force F
on each other. At what distance will these charges experience the same force in a
medium of dielectric constant K.​

Answer 1

Answer:

the coulomb is the equivalent of one ampere-second. Conversely, an electric current of A represents 1 C of unit electric charge carriers flowing past a specific point in 1 s.
