Three charges, q1, q2, and q3, are all initially infinitely far apart, and will be brought one at a time to the corners of an egulateral triangle with side length of 8.7 m.
(a) Find the work done to bring the first particle, q1 = 3.0 pC, to P From infinity.
(b) Find the work done to bring the second particle, q2 = 5.0 pC, to Q from infinity.
(c) Find the work done to bring the last particle, q3 = 8.0 pC, to R from infinity.
(d) Find the total potential energy gored in the final configuration of q1, q2, and q3.
