Two idencial point charges (q = 7.40 x 10^6 C) are fixed at diagonally opposite corners of a square with sides of length 0.440m. A test charge (q = 2.30 x 10^8 C), with a mass of 7.25 x 10^8 kg, is released from rest at one of the empty corners of the square. Determine the speed of the test charge when it reaches the center of the square.

Simple. What is the potential at the starting corner?
ans: 2kq/.440
What is the potential at the center?
ans:2kq/(.440*.707)
What is the KE at the center?
Ans: (voltsfinalvoltsinitial)qtest
