Question

19. Three identical particles, each possessing the mass m and charge + q. are placed at the corners of an equilateral triangle with side ro. The particles are simultaneously set free and start flying apart symmetrically due to Coulomb's repulsion forces. The work performed by Coulomb's forces acting
on each particle until the particles fly from one another to a very large distance is (where k =1/4πE0.)
(A) 3kq^2/r0
(B) kq²/r0
(C) 3kq²/2r0
(D) kq²/2r0
