Multiple steps, but they are all based on the same problem
1. Electric charges q1= -2.00x10^-6 C and q2= 3.00x10^-6 are held in place at thepositions x=0 and x=2 m, respectively, on the x axis. Find the magnitude and direction of of the electric field at point A with coordinates x=2m and y=2m.
2. Consider the same two charges as in the previous problem.
A) Find the electric potential at the point A with coordinates X=2.00M and Y=2.00M.
B) Suppose a charge q=4.00x10^-6C with mass 1.00x10^-2Kg were released from rest at the point A. what speed will this charge have acquired when it is far away from the charges q1 and q2?
C) Explain why it was not possible to use the result of question 1 to find this speed.
