(solution) Three charges are to be placed as follows: q1: 10.00 C at

Three charges are to be placed as follows:

q1: 10.00 µC at (0.00,0.00)

q2: -22.00 µC at (4.00,0.00) and

q3: -4.00 µC at (0.00,-3.00)

please help with question c, d alone thanks

answer to A was0J , answer to B was -0.49 J

Each charge will be placed at its coordinates in this order.

A) How much work is required to place q1 at (0,0)?

(Assume q2 and q3 are an infinite distance away).

B) With q1 now in place, how much work is required to place q2 at (4,0)?

(Assume q3 is an infinite distance away).

Hint: What is the final electric potential energy between q1 and q2?

C) With q1 and q2 now in place, how much work is required to place q3 at (0,-3)?

D) Calculate the electric potential energy of the group of three charges.
