Please do part a and b

(10\%) Problem 8: A variety of electric charges has been placed at distinct points along a line with separations as indicated. All charges have the same magnitude, and the sign is indicated explicitly such that \[ |+q|=|-q|=q \] A 50\% Part (a) Assuming that the potential energy of the system would be zero for the case \( q=0 \) system of charges for \( q>0 \). \[ U= \]
