Unit of permittivity is …….

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
We have `F=(1)/(2pi in_(0))(q_(1)q_(2))/(r^(2)) rArr in_(0)=(q_(1)q_(2))/(4pi Fr^(2))`
`therefore " Unit of " in_(0)=("Unit of " q^(2))/(("Unit of F")("Unit of " r^(2)))`
`thereofre` Unit of `in_(0)=(C^(2))/(Nm^(2))=C^(2)N^(-1)m^(-2)`
