(Answered) Three charges q1 q2 and q3 are all initially infinitely

Academics

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.

(d) Find the total potential energy gored in the final configuration of q₁, q₂, and q₃.
