In Coulomb's law, the constant of proportionality K has the units

A

`C^(-2) Nm^(2)`

B

`C^(2) N^(-1)m^(-2)`

C

`C^(2) Nm^(2)`

D

`C^(-2) N^(-1)m^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`F=1/(4piepsilon_0).(q_1q_2)/(r^2)implies1/(4piepsilon_0)=(Fr^2)/(q_1q_2)=Nm^2C^(-2)`
