Answer all problems please

Problem I5: In the coordinate system shown in the figure. particle l with charge y; '1' .~' uC is located at coordinates [le-lt [-3. O) m and particle 2 with charge (13 -I' pC is located at coordinates {x14 3) ( l1 0) In. 1 2 H {'3' 0] l1; 0) it;tllcmpcrttttcum Part (a) If you assume the potential vanishes at innity, the potential will be zero at some point (3020) with -3 m
