Three equal charges of `5.0 muC` each are placed at the three vertices of an equilateral triangle of side 5.0cm each. Calculate the electrostatic potential energy of the system of chages.

A

13.5 J

B

17.5 J

C

27J

D

15J

Text Solution

Verified by Experts

The correct Answer is:
A

`U=(1)/(4pi epsilon_(0)) ((3q^(2))/(r ))`
`=9 xx 10^(9) xx ((3xx5 xx 10^(-6) xx 5 xx 10^(-6)))/(5xx10^(-2)) =13.5J`
