Question

calculate the potential energy of a system of charge and also calculate when chares are more than two

please help me guys ​

Answer 1

Explanation:

Distance between each particle is a.

Charge on each particle is q.

So, potential energy U=U

12

+U

23

+U

13

=3U

12

(∵ U

12

=U

23

=U

13

)

⟹ U=3×

a

kq
