Question

1)Three charges q1=15mC, q2=8mC and q3=-12mC are assembled from infinitely far away to the locations q1(3,4); q2(-3,1) and q3(2,-1) with the locations indicated in cm as (x,y) for each of the charges.

a) At these locations, what is the charge collection%u2019s electric potential energy, U?

b)What electric potential energy will a fourth charge q4=4mC and located at the origin with respect to the other three charges experience?

c)What voltage , V, would q4 experience due to those other three charges q1,q2,q3?

d)What is the potential, V, AT POINT (2,2) Due to all four charges?
