?:?i5x.?^?i5x.Part A

What is the electric potential at the center of the square?

Make the usual assumption that the potential tends to zero far away from a charge.

Express your answer in terms of , , and appropriate constants.

Part B

What is the contribution to the electric potential

*energy*of the system, due to interactions involving the charge ?Express your answer in terms of , , and appropriate constants.

Part C

What is the total electric potential energy of this system of charges?Express your answer in terms of , , and appropriate constants.

, plz i want just the final answers , thanks

Part A:Part B:part E ,

, what about part D ??

Part E: when 2q is far away it is neglected and theremaining three charges are considered

please see

I corrected the calculation of total potential energyinvolving 2q as below and updated it ;

So I am correcting the step below

*2

part (c)

part C

part B:

partC:

Note I already corrected and updated my originally submittedsolution

_{tot}=q/k* [1/( d /) +1/( d /)+1/( d /)-1/ ( d /)]_{tot}=(-3q)/k*[ (q/d) + (5q/d) +(2q/d)]
