What is the potential energy of the equal positive point charges of `1 mu C` each held `1 m` apart in air ?

A

`9 xx 10^(-3) J`

B

`9 xx 10^(-3)eV`

C

`2 eV//m`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
A
By using `U = 9 xx 10^(9) (Q_(1)Q_(2))/(r )`
`rArr U = 9 xx 10^(9) xx (10^(-6) xx 10^(-6))/(1) = 9 xx 10^(-3) J`
