Three point charges are arranged at the vertices of an equilateral triangle ABC of side l. Charges at A, B and C are +q, +4q and -6q, respectively.
(i) Calculate electric potential energy of this system.
(ii) Charge at A is moved to the midpoint of AB, charge at B is moved to midpoint of BC and charge at C is moved to midpoint of CA. Calculate electric potential energy of this system now.
(iii) What work is needed to shift the charges to new locations as described in part (ii)?
