How r u??

Here's ur answer

The total energy of the system will be the sum total of the KE and PE of both the charges

Charge in the centre :

KE = 0J (It is not moving and is at rest)

PE = -kq₁q₂/r = -kq²/r

Charge revolving around the charge :

PE = 0

KE = -kq²/r

Therefore the total energy of the system is -2kq²/r
