What is the potential energy of two equal negative point charges `2 muC` each held 1m apart in air ?

A

`0.018 J`

B

`0.036 J`

C

zero

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`P.E. = (q_(1) q_(2))/(4pi in_(0) r) = (9xx10^(9) (-2xx10^(-6))^(2))/(1)`
= 0.036 J
